With Unrein out, the Bears are likely to play former Florida standout Jonathan Bullard, their third-round pick of the 2016 draft, in a key role.

Cornerback Deiondre’ Hall, who was ruled out on Friday, also did not join the team in Tampa.

The Bears signed fullback Paul Lasike to the active roster, taking the 53rd spot which had remained open. Receiver Marquess Wilson was a candidate to join the roster off the PUP list, though he is not quite ready to return.

Wilson had his 21-day window to return from the PUP list opened on Monday when he returned to practice.

“I thought he looked healthy,” Bears coach John Fox said on Friday. “Now it’s a matter of getting back into football shape. You can do all kinds of conditioning, you can all kinds of rehab but there’s nothing really like practicing and playing the game. He had a good first week from that standpoint.”

The Bears have listed Eddie Royal, Eddie Goldman, Pernell McPhee, Bryce Callahan and Tracy Porter as questionable for Sunday’s game. Pro Bowl guards Kyle Long and Josh Sitton were each cleared.

Kickoff between the Bears and Buccaneers comes at noon CT from Raymond James Stadium in Tampa.
