CHARLOTTE – Linebacker Shaq Thompson (foot) is among five Panthers listed questionable but expected to play in Sunday's game against the Buccaneers.
Thompson, who has missed the last two games, was a limited practice participant throughout the week.
Guard Trai Turner (concussion) is out for the second straight week, but Rivera has been encouraged by his recent progress through the protocol.
"He felt good this morning, so the next step was to get him outside and have him shuffle around a little bit," Rivera said. "Each day that process will continue."
Veteran Amini Silatolu is set to start again in place of the two-time Pro Bowler.
"Very pleased," Rivera said when asked about Silatolu's performance against the Packers. "He had one big mistake, and that was a communication thing. But other than that, very confident. Amini has played for us and played well. We feel confident and comfortable that he is going to continue that trend for us."
The Panthers also made a roster move Friday, signing wide receiver Mose Frazier off the practice squad and onto the 53-man roster. Carolina had an open spot it had to fill per NFL rule with linebacker Thomas Davis on the suspended list this week.
Frazier isn't expected to be active, unless Funchess or Shepard is not. The University of Memphis product hasn't played in a regular season game.
