Mark Sanchez expected starter as Eagles ready for Lions on Thanksgiving

— -- Mark Sanchez is expected to start at quarterback for the Philadelphia Eagles' Thanksgiving game in Detroit, a league source tells ESPN's Adam Schefter.

Regular starter Sam Bradford passed the concussion protocol this week but is still bothered by a sprained joint in his left (non-throwing) shoulder.

Sanchez started last Sunday's game against Tampa Bay, a 45-17 loss for the Eagles in which he threw three interceptions.

Bradford had "some memory loss" after sustaining a concussion earlier this month and said Tuesday that the separated shoulder could keep him from playing Thursday against the Lions.

Regarding his head injury, Bradford said "the symptoms I've had were similar to the ones I've had in the past, and I was able to recover from those."
