Carter (knee) was placed on season-ending injured reserve Saturday, Lindsay Jones of USA Today reports.

Carter has been hampered by injury throughout his NFL career. After a promising rookie season, the fourth round draft pick essentially missed the entirety of the Broncos' next two seasons while recovering from microfracture knee surgery. Carter played in 11 of Denver's first 12 games this season, at which point his knee began to become an issue yet again. The Broncos needed to make some roster moves to free up spots for Danny Trevathan and Dominique Jones on the team's 53-man roster. Carter may have played his last snap as a Bronco.

Broncos DC Jack Del Rio said SS Quinton Carter (knee) "looks pretty good."

Carter hasn't appeared in a game since Week 3 of the 2012 season due to knee issues. He had microfracture surgery before suffering a setback last summer. Carter has spent the past two seasons on I.R. The Broncos' website believes Carter could compete with Rahim Moore for the starting job next to T.J. Ward. If the Broncos get anything out of Carter, it'd be viewed as a positive.

Broncos SS Quinton Carter's felony gambling charges have been dropped by prosecutors in Nevada.

Carter was charged on March 9 with three counts of a "fraudulent act against a gaming casino," after allegedly betting $5 chips too late on a craps table. Carter missed most of 2012 with a knee injury, but coach John Fox recently described his recovery as "fantastic." He'll compete for a roster spot in 2013.

Broncos SS Quinton Carter was arrested last weekend in Las Vegas on felony charges that he cheated in a casino craps game.

Carter was arrested on Saturday night on the accusations that he added money to his bets after the dice had rolled. He has been charged with three counts of fraudulent act in a gaming establishment and faces up to 18 years in prison. Carter, at the time of his arrest, also had a warrant for failure to complete counseling after a misdemeanor marijuana possession charge from 2011. Carter played in just two games last season before a knee injury landed him on injured reserve.

Broncos coach John Fox told reporters at the Combine that SS Quinton Carter's recovery from knee surgery is "going fantastic."

"His rehab's going great," Fox emphasized. When Carter was placed on I.R. late last September, it was feared he'd require microfracture surgery on his right knee. An August scope hadn't fixed the joint. Carter will be back to compete for playing time in Denver, but this is a position the Broncos can upgrade.

Broncos placed safety Quinton Carter (knee) on injured reserve, ending his season.

Carter had his right knee scoped in early August and is now facing the possibility of microfracture surgery. A second-year player out of Oklahoma, Carter started 10 games for the Broncos in 2011 and accumulated 56 tackles. He has played mostly special teams in 2012. The Broncos now have Jim Leonhard and David Bruton behind starters Mike Adams and Rahim Moore.

Broncos SS Quinton Carter will miss at least two preseason games after having his knee scoped this week.

Carter got injured during an indoor practice on July 27, just as the Broncos had opened camp. He injured both his hamstring and knee, and had surgery on the latter. While it was just a "scope," Carter may now cede his starting job to Rahim Moore. Mike Adams is running as the Broncos' starting free safety in camp.

FS Quinton Carter sustained a hamstring pull in the Broncos' Week 16 loss to the Bills.

The Broncos suddenly have major concerns at the safety spot heading into their showdown with the Chiefs. With Brian Dawkins (neck) also hurting, they may be forced to start backups Raheem Moore and David Bruton.

Broncos FS Quinton Carter suffered a concussion in the second quarter of Sunday's loss to the Lions.

Carter had just overtaken fellow rookie Rahim Moore for the starting gig a few weeks ago. He'll need to go through the NFL's concussion procedures before regaining his starting job.

Broncos signed No. 108 overall pick Quinton Carter to a four-year, $2.49 million contract.

Carter is coming off an All-America selection after a fantastic season at Oklahoma. More of a long-term NFL prospect, he'll likely start out on special teams behind veterans Brian Dawkins and Renaldo Hill.
