Carolina's injury report indicates Olsen participated in all of the team's practice on Wednesday.
Coach Ron Rivera says Olsen's status will help offensive coordinator Mike Shula with game planning for Sunday's game knowing "there's not going to be a pitch count as far as the number of plays" when it comes to the tight end.
Olsen missed eight games while on injured reserve with a broken foot. He returned to action two weeks against the New York Jets but only played one quarter before leaving with soreness in his foot.
The Panthers held Olsen out of last week's game against the New Orleans Saints because of playing on an artificial surface.
