Drew Stanton was the second of three Lions quarterbacks to miss Monday's practice due to injury concerns.

Arguably the team's most impressive quarterback during the preseason, Stanton has managed a team best passer rating of 111.8 in his three performances but could miss the preseason finale at Buffalo.

Stanton, who missed his rookie campaign after undergoing knee surgery, experienced what head coach Jim Schwartz deemed "a lot" of swelling in his knee prior to Monday's practice.

He is expected to miss Tuesday's practice as the Lions await MRI results.

"He had nothing after (Saturday's) game and had a little bit of swelling on Sunday, but it was nothing major," said Schwartz. "Today he came in this morning with a lot of swelling; so we sent him for an MRI and don’t have the results yet, but obviously he wasn’t able to come out here today."
