Welker has reportedly been cleared by Dr. Stanley Herring -- one of the nation's leading concussion experts -- to continue his NFL career, 9news.com reports.

To date, Welker has had just one free agent visit, with the Dolphins, who ended up signing Greg Jennings, but the veteran wideout -- who turns 34 on Friday -- could well catch on somewhere as a slot option once the dust settles following the NFL draft. In 14 games for the Broncos in 2014, Welker recorded 49 catches for 464 yards and two TDs.

Welker is set to meet with the Dolphins on Wednesday, NFL.com reports.

Free agent interest in the 33-year-old wideout has been cool thus far, but if Welker returns to Miami -- where he played between 2004 and 2006 -- he could provide the team with valuable depth and experience, though his days of racking up elite numbers out of the slot are probably over. In 14 games for the Broncos in 2014, Welker caught 49 passes for 464 yards and two TDs.

Welker is unlikely to be back with the Broncos in 2015, Troy Renck of the Denver Post reports.

Demaryius Thomas and Emmanuel Sanders are entrenched as the top two wide receivers, and the Broncos presumably want 2014 second-round selection Cody Latimer to be a part of the offense in his second season. Even if he does end up back with the Broncos, Welker will likely just be fourth or fifth on the depth chart, after undeniably declining over the past two seasons.

Welker denied reports that he was considering retirement Monday, telling the Denver Post that he is "just getting ready for 2015."

Welker has dealt with numerous concussions over the past few years and is coming off a season in which he caught only 49 passes for 464 yards and two touchdowns in 14 games, his lowest yardage total since 2005. He'll become a free agent next month, and while the Broncos could re-sign him, it appears more likely that they'll try to get 2013 second-round pick Cody Latimer more involved in the offense behind Demaryius Thomas -- who is likely to be hit with the franchise tag -- and Emmanuel Sanders.

Welker is reportedly considering retirement, foxsports.com reports.

Between a series of head injuries that he has endured over the past few seasons and his declining production of late, the report indicates that Welker has entertained the notion of calling it a career. For his part, a day after the Broncos were eliminated from the playoffs, when asked about a potential return to the team, the wideout replied,"I don't know. There are a lot of things I've got to figure out in the offseason." Meanwhile, the Denver Post speculates that it's unlikely that the Welker will return to the Broncos. The 33-year-old slot receiver, who is in line to become a free agent next month, caught 49 passes for 464 yards and two TDs in 14 games this past season.

Welker had two catches on two targets for 42 yards Sunday against the Raiders.

After catching 73 passes on 111 targets for 778 yards and 10 touchdowns in 13 games last season, Welker really struggled this year, catching 49 passes on 64 targets for 464 yards and two scores. Quarterback Peyton Manning greatly prefers to throw to wideouts Demaryius Thomas and Emmanuel Sanders, plus tight end Julius Thomas, leaving fewer targets for Welker as they head into the playoffs.

Welker (ankle) had two catches on three targets for 16 yards Sunday against the Chargers.

The Broncos ran the ball 39 times versus only 22 pass attempts, and with Demaryius Thomas getting 11 targets, there just weren't enough balls to go around for Welker to make much of an impact. Welker has scored just two touchdowns all season, and he's failed to reach even 20 receiving yards in three of the last four games, making him a very unreliable fantasy option in Week 16 against the Bengals.

Welker (ankle) is listed as active for Sunday's game against the Chargers.

Welker is out there, as expected, but with Demaryius Thomas and Emmanuel Sanders also in the Broncos' wideout mix, the veteran slot man has been a hit-or-miss fantasy option of late.

Welker (ankle) is listed as probable for Sunday's game against the Chargers, the Broncos' official site reports.

Welker should be a go Sunday after practicing fully Friday, but his production this season has been sporadic, with Demaryius Thomas and Emmanuel Sanders also in the Broncos' wideout mix.

Welker (ankle) returned to practice Thursday, ESPN's Jeff Legwold reports.

Welker thus appears to be on track to play Sunday against the Chargers. He's coming off a six-catch, 82-yard effort in Week 14, but his production this season has been sporadic, which limits his utility to deeper formats.

Welker (ankle) did not practice Wednesday, ESPN.com reports.

We'll revisit Welker's status Thursday, but the report suggests that the wideout should be ready to play Sunday against the Chargers. Welker caught six passes for a season-high 82 receiving yards in Week 14's win over the Bills.

Welker had six catches on six targets for a season-high 82 yards during Sunday's win over the Bills.

The Broncos' air attack was very limited Sunday, as quarterback Peyton Manning threw only 20 passes, none of which went for touchdowns. Welker led the team in receiving yards and co-led them in targets with Emmanuel Sanders. It was a decent output for Welker, though hardly one that moved the fantasy needle. He'll look to keep his positive momentum going in Week 15 against the Chargers, who he had only five yards against back in Week 8.

Welker caught 1-of-2 targets for 12 yards in Sunday's 29-16 win over the Chiefs.

Welker converted a 3rd-and-10 during the first quarter, and then went missing for the rest of the day. Even with Julius Thomas (ankle) sidelined, Welker hasn't seen many targets, as the Broncos seemingly prefer to just throw even more passes to Demaryius Thomas and Emmanuel Sanders.

Welker had four catches on four targets for 18 yards and a touchdown Sunday against the Dolphins.

The touchdown was Welker's second this season, though he's failed to reach the 65-yard mark in any game. Demaryius Thomas (10 catches on 13 targets for 87 yards and three touchdowns) and Emmanuel Sanders (nine catches on 13 targets for 125 yards) continue to dominate the looks from quarterback Peyton Manning, which keeps Welker's fantasy upside fairly limited.

Welker had four catches on six targets for 28 yards Sunday against the Rams.

Welker continues to be a shell of what he was last season, as he has yet to record more than 60 yards in a game this season, while catching just one touchdown in eight games. However, he could see a spike in usage in Week 12, as Emmanuel Sanders could miss out after suffering a concussion on Sunday.

Welker (back) had four catches on five targets for 24 yards Sunday against the Raiders.

After getting knocked out of last Sunday's game against the Patriots with a lower-back injury, Welker was able to practice fully all week, though that did little for his fantasy production Sunday. Welker has been a shell of what he was last season, failing to reach 65 yards in a game this season while scoring just one touchdown.

Welker (back) is listed as active for Sunday's game against the Raiders.

Welker is out there if you need him this week, though with fellow wideouts Demaryius Thomas and Emmanuel Sanders both seeing plenty of targets in the Denver offense, Welker has been a hit-or-miss option of late.

Welker (back) is probable for Sunday's game against the Raiders, the Broncos' official site reports.

After practicing fully all week, Welker looks like a go this week, though of late, his production has been sporadic, with fellow wideouts Demaryius Thomas and Emmanuel Sanders both seeing plenty of targets in the Denver offense.

Welker (back) practiced fully Wednesday, the Denver Post reports.

Welker, who absorbed a hit to his lower back this past Sunday, thus appears on track to play this weekend against the Raiders, barring any setbacks.

Welker (back) is considered day-to-day moving forward, USA Today reports.

Welker was knocked out of Sunday's loss to the Patriots after taking a considerable blow to his lower back. Fortunately, Welker avoided a serious injury and should return to the field soon. While his practice involvement will be monitored throughout this week, Welker's current day-to-day status is certainly encouraging for his availability this Sunday against the lowly Raiders.
