Bradford has yet to pass the NFL's concussion protocol, so he won't practice Thursday.
With Bradford also dealing with left shoulder issue in addition to his concussion, he continues to look pretty iffy for Sunday's game against the Bucs. In the event that he is ruled out for the contest -- and such an outcome could arrive Friday upon the release of the Eagles' final Week 11 injury report -- Mark Sanchez would be in line to start at QB in his place this weekend.
