The Lions entered Saturday’s game with injury concerns at the cornerback spot. The team’s secondary has now suffered another notable loss. 
Amik Robertson exited Detroit’s ongoing divisional round game against Washington early in the contest. He has quickly been ruled out as the result of an elbow injury, and NFL Network’s Tom Pelissero notes he has been taken to hospital for further evaluation. The Lions will be shorthanded to an even further extent moving forward as a result.
Carlton Davis is out for tonight and is not expected to return to the lineup even if Detroit makes it to the Super Bowl. His absence has been sorely felt since he suffered a broken jaw in Week 15, and Robertson was leaned on heavily down the stretch as Detroit locked up the No. 1 seed. Especially with second-round rookie Ennis Rakestraw Jr . inactive despite having been activated from injured reserve ahead of tonight’s game (and with Emmanuel Moseley on the NFI list ), cornerback will be a spot to watch closely for the Lions.
Terrion Arnold suffered a foot contusion in Week 18, but Detroit’s win in that game gave the team a first-round bye. Having benefitted from the extra rest time, the Lions’ top pick in April’s draft is healthy and taking part in Saturday’s contest. He along with Kindle Vildor will be counted on the rest of the way while the team awaits updates on Robertson’s status.
The 26-year-old played out his rookie contract with the Raiders ahead of his first trip to free agency. Robertson signed a two-year, $9.25MM pact to head to Detroit, and he provided his new team with roughly the same contributions in terms of snap share as his old one this year. The Louisiana Tech product posted 50 tackles and eight pass deflections across 17 games in his debut Lions campaign. Whether or not he will be an option to play next weekend (if applicable) will depend his prognosis.
