Following Tuesday's practice, the Detroit Lions made a pair of roster moves, both involving the injured reserve list. Specifically, they put offensive lineman Darren Keyton on IR, and they also released tight end David Ausberry from IR.
Keyton's move to injured reserve is no surprise given that he suffered a "significant" knee injury in the Lions' preseason opener last week. The injury came on Keyton's first and only play of the game, and it resulted in him being carted to the locker room.
Keyton was fighting for the final backup spot on the interior offensive line, but he was a long shot even before his injury. Taylor Boggs stepped up to jump to the front of the pack in that position battle last week, and Keyton also faced competition from Braxston Cave and undrafted free agents Torrian Wilson and Al Bond. Now, the Lions will presumably add another interior lineman to their roster with Keyton on injured reserve.
As for Ausberry, he was put on injured reserve last week with what turned out to be a broken finger. Since this isn't exactly a season-ending type of injury, Ausberry was released with an injury settlement, allowing him to potentially land with another team this season.
UPDATE: It turns out that Keyton isn't officially on injured reserve just yet.
The #Lions have actually waived/injured C Darren Keyton. If he clears waivers by 4 pm tomorrow he'll be placed on their IR.— Tim Twentyman (@ttwentyman) August 18, 2015
