Bears being coy about Kyle Fuller's status for this Sunday

LAKE FOREST, Ill. -- Chicago Bears receiver Eddie Royal (toe), left guard Josh Sitton (ankle) and linebackers Willie Young (knee) and Leonard Floyd (concussion) are among the players listed as questionable to play against the San Francisco 49ers this Sunday.

The Bears also have until Saturday afternoon to add cornerback Kyle Fuller to the active roster. Chicago designated Fuller as their one player eligible to return off of injured reserve, and officially opened his 21-day practice window on Wednesday.

Bears coach John Fox said Fuller held up OK at practice.

“He made it three days in practice,” Fox said. “No setbacks. He seems to be adapting pretty well. He has another practice [Saturday] and we don’t have to make a decision until 3 p.m. CT because of where he is on the roster. We’ll evaluate that after tomorrow.

“If you feel like he makes you better, that’s a move you make. Now we’re just working through him medically, durability-wise, and how much he can play.”

A former first-round pick, Fuller started 30 games from 2014-15, intercepting six passes and forcing three fumbles.

Meantime, safety Adrian Amos (foot) and cornerback Deiondre Hall (ankle) are also questionable for the Niners game.
