Linebacker Koa Misi's season with the Miami Dolphins ended two days before the start of training camp.A starter since his rookie season in 2010, Misi was placed on injured reserve Ryan Tannehill Jerseys Tuesday Jay Ajayi Jerseys after he failed to receive medical clearance. His 2016 season was limited to three games because of a neck injury that could be career ending.The Dolphins also signed cornerback Alterraun Verner, an eight-year veteran who started 70 games for the Titans and Buccaneers. Ndamukong Suh Jerseys He is expected to compete for playing time at slot cornerback. The loss of Misi leaves Miami even thinner at linebacker, perhaps the team's most worrisome area. Injuries ravaged the linebacker corps last season.“We've got a lot of guys that have played — I know that, because everybody had to play last year," coach Adam Gase said before the loss of Misi was announced. “I feel better probably than a lot of people do outside of our building. I like our guys. I saw Cameron Wake Jerseys a lot of good things in the spring. I feel like we look a lot different Jarvis Landry Jerseys than we did last year, when you get to the twos and threes, with the competition."Another question mark is center, where Mike Pouncey's participation in camp is expected to be extremely limited.Pouncey is a three-time Pro Bowler even though he hasn't played a full season since 2012. Despite little practice time last year, he was so effective in the five games he played that Gase says he would be comfortable starting Pouncey in the season opener even if he sits out all of camp.Pouncey, however, gets restless on the sideline.“He wants to practice and go through his routine for training camp," Gase said. “I was amazed by the fact that he missed as much time as he did last year during the season and walks right back in and plays at an elite level. I'm always going to listen to him. It's his body and his mindset. I trust what he tells me."Quarterback Ryan Tannehill returned during offseason workouts from a knee injury that ended his 2016 season, and he'll take part in camp with no restrictions. Pouncey has had surgery on both hips.
