Detroit Lions

Ngata heads into his 12th NFL season with no health issues, Mike O'Hara of the team's official site reports.

The veteran defensive tackle wanted to make sure he was completely healthy heading into the new season and even underwent neurological exam to determine if he has sustained any brain damage over his career. The results showed no brain damage, according to the defensive tackle. "The brain is good to go...I wanted to make sure my head was good. He (the neurologist) said everything was pretty good - really good, actually...Just to make sure, with all things that are going on with the brain and stuff throughout the league, I don't want to have problems when I'm older", Ngata said. The defensive tackle missed some time last year due to calf and quad issues but still managed to record 22 tackles and 1.5 sacks through 13 games.

Wells (knee) was waived by the Lions on Tuesday.

Wells finished last season on injured reserve after tearing his ACL during the preseason. He will try to get healthy and earn a chance to work his way onto an NFL roster during this coming preseason.

The Lions informed Ebron that they would exercise his fifth-year option, Michael Rothstein of ESPN.com reports.

The organization was on the fence about committing to Ebron through 2018 after a mostly disappointing first two seasons in the league, but the Lions apparently saw enough growth in his performance in 2016 to justify keeping him in the fold a little longer. Aside from adding Michael Roberts in the fourth round of last weekend's NFL draft, the Lions haven't made many major additions at tight end during the offseason, so Ebron once again looks primed to open the upcoming campaign as the team's starter. His 2016 totals of 61 catches and 711 yards were nice, but he'll need to elevate his touchdown total (one) if he hopes to become an upper-tier fantasy tight end.

Thomas signed a contract with the Lions on Monday, NFL.com reports.

Thomas is coming off a highly productive 2016 season with Connecticut in which he recorded 1,179 yards and three touchdowns on 100 receptions. He has a chance to earn a role as a depth receiver with Detroit in 2017.

Rector signed a contract with the Lions on Monday, NFL.com reports.

Rector spent the past four seasons playing for Stanford. He finished the 2016 campaign with 367 yards and three touchdowns on 32 receptions. He'll compete for a depth receiver slot with Detroit in 2017.
