Maurkice Pouncey is relieved to be back on the field after a horrific 2015 season that saw him undergo six surgical procedures and a skin graft.

Pouncey was previously a Pro Bowl center.

Pouncey broke his left fibula in the preseason when Green Bay Packers safety Ha Ha Clinton-Dix fell onto the back of his leg. Packers receiver Jordy Nelson also tore his anterior cruciate ligament in that Aug. 23 game.

Pouncey suffered a setback in October. The surgical wound didn't close properly, resulting in a staph infection.

Breshad Perriman does not have a fully torn ACL in his left knee as originally feared and will be ready for the 2016 season.

Perriman received a stem cell injection from noted orthopedist James Andrews, according to a source informed of his situation.

A 2014 first-round pick of the Baltimore Ravens who missed all of his rookie season with a right knee injury, he had his latest setback on the final day of OTAs.

Darren McFadden will undergo surgery on a broken elbow and miss a "couple months."

McFadden suffered the injury in an accident at his house over Memorial Day weekend but participated last week in organized team activities with the Dallas Cowboys.

McFadden will compete for carries this season with Ezekiel Elliott. 

Jamaal Charles will return to the Kansas City Chiefs' practice field on Tuesday for the first time since suffering a torn ACL.

Charles suffered the injury on Oct. 12th.

Fellow running backs Spencer Ware and Charcandrick West signed contract extensions this offseason to help insulate the Chiefs in case of another injury like the one Charles suffered in 2015.

Breshad Perriman has suffered a partially torn ACL in his left knee and will undergo surgery in the coming days.

Perriman injured his knee on the last day of the Ravens' OTAs.

Perriman suffered a posterior cruciate ligament sprain in his right knee on the first day of training camp last season and missed all 16 games.

Brandon Boykin may have a career-threatening hip injury.

Boykin, 25, was signed and released by the Carolina Panthers this off-season after spending the 2015 season with the Pittsburgh Steelers, during which he recorded 25 tackles, one sack and one interception. Boykin made visits with the Dallas Cowboys and Atlanta Falcons following his release.

Boykin has logged 146 career tackles with eight interceptions and one touchdown in his NFL tenure.

Aqib Talib was released from a Dallas hospital on Monday afternoon after spending two nights because of gunshot wounds.

According to a Dallas police report, the bullet entered through the rear of Talib's right thigh and exited out his right calf.

Police are still investigating, but Talib has told people close to him that he shot himself by accident.

"Everything was a blur and I was too intoxicated to remember what happened," Talib reported told police.

Colin Kaepernick won't be cleared to participate with the San Francisco 49ers during their minicamp.

The hope is Kaepernick will be cleared when camp opens at the end of July.

Offensive coordinator Curtis Modkins admitted last week he had "no idea" when the quarterback would be cleared.

Kaepernick will likely need to be substantially better than Blaine Gabbert in camp and in the preseason to win the job back.

Maliek Collins will miss the next 10 to 12 weeks after undergoing surgery to repair a broken foot.

Collins was a third round pick by the Dallas Cowboys at defensive tackle.

Collins' break is similar to the one Dez Bryant suffered last year to his fifth metatarsal. Collins had a screw inserted into the foot to stabilize the joint, plus a bone graft.
