Starting right guard Chris Scott (sprained knee) and backup Jeff Byers (foot) suffered injuries in the second quarter of Sunday's 34-10 victory over the Atlanta Falcons that extended Carolina's winning streak to four straight.
UPDATE: Scott is listed as day-to-day. Byers is out after having Lisfranc surgery on Monday.
Nate Chandler, a backup swing tackle who was signed as an undrafted free agent out of UCLA to play defensive line last year, was in for 41 plays the remainder of the game.
With Bell and Byers both questionable for this week -- with the biggest concern for Byers -- the Panthers (4-3) will begin the week with Chandler as the starter.
"Nate played well,'' coach Ron Rivera said on Monday.
Chandler made the move to the offensive line after moving over to help on the practice squad last season. Line coach John Matsko liked what he saw and asked Rivera if he could try him there permanently.
"He took the challenge and he's been solid there ever since,'' Rivera said.
