Coker (quadricep) was a non-participant at Wednesday's practice, Darin Gantt of the Panthers' official site reports.
Coker was a late addition to the Panthers' injury report last Friday due to a quad issue that left him questionable for Week 12 action. He eventually was deemed inactive for this past Sunday's game against the Chiefs, and he now has missed two straight practice sessions as a result of the injury. Head coach Dave Canales told Joe Person of The Athletic on Wednesday that he doesn't expect Coker to be available Sunday versus the Buccaneers, something that may be confirmed by the time Carolina posts its final report of the week Friday.
