The word from tight end Greg Olsen after last Sunday’s game against the Jets was that his foot would be OK even though he left early in his first game back from a broken bone in the foot. Further tests showed nothing to contradict that assessment, but soreness in the foot kept Olsen from practicing with the team to start the week. That remained the case on Thursday and Friday as well, but Panthers coach Ron Rivera said Olsen could play without practicing and the team has listed him as questionable to face the Saints.
