Mayo was on the field for 16 of the Patriots' 72 snaps on defense in Sunday's win over the Bills, ESPN's Mike Reiss reports. Mayo recorded two tackles in the contest.

Fellow Patriots' linebackers Jamie Collins and Dont'a Hightower are fantasy factors these days, but until Mayo gets increased snaps, he's off the fantasy radar.

Mayo was on the field for just 11 of 73 defensive snaps in Thursday's season opener against the Steelers, ESPN.com reports.

Fellow linebackers Jamie Collins (73 snaps ) and Dont'a Hightower (61 snaps) were busier than Mayo on Thursday, with Mayo recording just two tackles in the contest. We'll revisit Mayo's snap count in Week 2, but until he sees the field more, he's only an option in deeper IDP formats.

Mayo was on the field for 15 of 76 defensive snaps in Friday's preseason game against the Panthers, ESPN.com's Mike Reiss reports.

In his limited time on the field Friday, Mayo recorded four tackles, while csnne.com notes that the veteran LB showed well against the Panthers' starters in his first game action since last October when he tore his patella tendon. Mayo is slated to start at middle linebacker for the Patriots this season, an assignment that provides him with IDP utility, thanks to his knack for racking up tackles when healthy.

Mayo (knee) was in uniform, but did not play against Green Bay in Thursday's preseason opener, the Boston Globe reports.

The same applies to fellow linebacker Dont'a Hightower, but assuming no injury setbacks, Mayo is in line to start at middle linebacker for the Patriots. It's an assignment that provides Mayo who recorded 53 tackles in six games last season with a degree of IDP utility thanks to his knack for racking up stops.

Mayo -- who tore his patellar tendon last October -- is not yet 100 percent, ESPN.com reports.

Mayo, who recorded 53 tackles in six games for the Patriots last season, has yet to see the field through the team's OTAs and minicamp and it's unclear how much work he'll be able to see once training camp starts. Once Mayo reestablishes his health, however, the 29-year-old is in line start at linebacker for the Pats, along with Dont'a Hightower and Jamie Collins.

Mayo (knee) has agreed to a restructured contract that will keep him with the Patriots this season, NESN.com reports.

Mayo's cap hit was set to exceed $10 million in 2015, but per the report, the 29-year-old has agreed to a one-year pact worth $4.5 million. Mayo's last two seasons have been slowed by injuries, but his experience and leadership are assets to the team's defense and assuming his health in 2015, Mayo -- who racked up 53 tackles in six games last season -- is in line start at linebacker for the Pats, along with Dont'a Hightower and Jamie Collins.

Mayo, who tore his patellar tendon in Week 6, indicated that his injury rehab has been going well, the Boston Herald reports.

While Mayo -- who landed on IR with the injury -- indicated he's "right on schedule" in his recovery, the linebacker isn't sure if he will be ready in time for the Patriots' offseason workouts, which begin in April. Prior to suffering his knee injury, Mayo recorded 53 tackles and one sack in six games for the Patriots. Per WEEI.com, Mayo -- who is signed through the end of the 2017 campaign -- is a candidate to have his contract restructured this offseason, given his cap hit of $10.6 million next season.

Mayo (knee) has been placed on IR by the Patriots, Ben Volin of the Boston Globe reports.

Running back Stevan Ridley was also placed on IR, allowing the Patriots to promote offensive lineman Chris Barker and running back Jonas Gray from their practice squad in advance of Thursday's game against the Jets.

Mayo underwent surgery Thursday to repair the patella tendon in his right knee, csnne.com reports.

The report indicates that Mayo's recovery is expected to take about six months, with the linebacker expected to land on IR in the coming days. His absence is a big blow to the Patriots' defense, and going forward, the team figures to lean heavily on the likes of Dont'a Hightower (health permitting) and Jamie Collins.

Mayo (knee) has been ruled out for the season, ESPN's Adam Schefter reports.

Mayo was carted off the field Sunday against the Bills after suffering a lower-leg injury. He underwent an MRI on Monday, and while the team has not provided an official diagnosis, Mayo's injury is severe enough that it will keep him out for the remainder of the 2014 season. This is the second consecutive year in which Mayo has suffered a season-ending injury, as he was lost to a torn pectoral a year ago to the day.

Mayo (knee) has been ruled out for Thursday's game against the Jets, the Boston Herald reports.

Mayo underwent an MRI on Monday and the expectation is that the yet-to-be-reported results will confirm a serious, and quite possibly season-ending injury, for the Patriots' linebacker.

Mayo was using crutches and sporting a compression sleeve over his right knee after Sunday's win over the Bills, ESPN.com reports.

We'll track Mayo's status in the coming days, but it looks like the linebacker is destined to miss time due to the injury, and perhaps a significant amount of it.

Mayo suffered an apparent leg injury in Sunday's game against Buffalo and was carted off the field, ESPN's Mike Reiss reports. He will not return.

This one didn't look good. The entire defense took a knee around Mayo while he was on the ground, and Bill Belichick went onto the field to check on one of the most important pieces of the Patriots' defense. Deontae Skinner replaced Mayo.

Mayo was on the field for 55-of-55 snaps on defense in Sunday's 43-17 win over the Bengals.

Mayo recorded eight tackles in the game, which brings his total through five games to 48, a mark that puts him in a tie for seventh place in the NFL in that category.

Mayo is no longer listed on the Patriots' practice participation/injury report, the team's official site reports.

Mayo missed practice Wednesday to be with his wife for the birth of their child, but he's back with the team and on track to play Sunday against the Raiders.

Mayo missed practice Wednesday to be with his wife for the birth of their child, the Boston Herald reports.

Mayo, who has 19 tackles and a sack through the Patriots' first two games, should thus be available for Sunday's game against the Raiders.

Mayo (unspecified reason) did not practice Wednesday, the Boston Herald reports.

We'll have to see how the Patriots list Mayo on on Wednesday's practice participation/injury report, but the linebacker was able to play all 68 snaps on defense in Week 2's win over the Vikings.

Mayo was on the field for 74-of-74 snaps on defense in Sunday's loss to the Dolphins, ESPN.com reports.

In the process, Mayo recorded 12 tackles, thus reestablishing both his health and his ability to record a good amount of stops for his IDP owners.

Mayo (undisclosed), who did not play in the Patriots' preseason finale, does not appear on the team's Wednesday practice participation/injury report.

Mayo thus appears to be a go for Sunday's game against the Dolphins, and assuming he can stay on the field this season, the linebacker is an IDP bounce-back candidate, thanks to his tackling ability.

Mayo (undisclosed) did not travel with the Patriots for Thursday's preseason finale against the Giants, the Boston Globe reports.

We'll have a better read on Mayo's Week 1 prospects next week when the team's official practice participation/injury report is made available, but at this stage the linebacker's status is worth monitoring by those in IDP formats.
