Burks (concussion) was listed as a non-participant on Thursday's practice estimate, Jim Wyatt of the Titans' official site reports.
Burks didn't practice Wednesday, so he's looking iffy at best for Sunday's game against the Panthers. If the wideout is ruled out for the contest, Nick Westbrook-Ikhine, Chris Moore and Kyle Philips would be in line to continue to see added snaps behind No. 1 WR DeAndre Hopkins this weekend.
