The Oakland Raiders could be without defensive end Arden Key for the remainder of the 2019 season. He suffered a broken foot injury during the team's 31-24 win over the Detroit Lions, according to Ian Rapoport of NFL Network. He is going to receive a second opinion from Dr. Robert Anderson to confirm the ‘initial view.'

There was some anticipation for what Key could provide the Raiders heading into the season. He felt that he improved as a pass rusher by furthering his technique by working with defensive line coach Brentson Buckner.

“I got a little stronger, which helps with the bull rush, and now that's my [baseline] move,” Key said during training camp, via Scott Bair of NBC Sports BayArea. “So much of the credit goes to Buck (defensive line coach Brentson Buckner). I'm really starting to use my hands now. Last year, I didn't use hands at all. I was using my shoulder and a lot of forearm. If I can use my hands to keep guys off me, I can make moves and use my bend and length and things of that sort.”

The work that Key put in over the offseason began to show for the Raiders during the Raiders' last two games. He recorded one sack in each of those performances and those are the only sacks that he has recorded in four appearances on the season.

The Raiders will need to wait until next season to see if their 3rd round pick from the 2018 NFL Draft can play at a level that they believe he can achieve.
