Coker (quadriceps) was a full participant in Wednesday's practice, David Newton of ESPN.com reports.
Coker also began Week 14 as a full participant at practice, before being downgraded to limited participation and then no participation in the Panthers' ensuing two practices prior to sitting out a third straight game in this past Sunday's loss to Philadelphia. Head coach Dave Canales expressed more optimism Wednesday that Coker won't take a step back in activity this week, noting that the undrafted rookie displayed an ability to attack routes that he was previously lacking, according to Steve Reed of the Associated Press. Coker will work to remain a full participant Thursday and Friday, and if he does, he'll return to action Sunday versus Dallas.
