Bradford (concussion/shoulder) is listed as inactive Thursday at Detroit, Geoff Mosher of CSN Philadelphia reports.
Although Bradford took part in a pregame warmup to test out his shoulder, he won't start and, in fact, not even suit up, missing his second consecutive contest. The Eagles will instead turn to Mark Sanchez under center.
Ertz (concussion) has been ruled out for Thursday's contest at Detroit.
With only three days to recover from a concussion suffered Sunday versus the Buccaneers, Ertz was able to progress to a limited showing in Wednesday's practice, according to Zach Berman of the Philadelphia Inquirer. However, he was unable to complete all phases of the league's protocol for head injuries. His next opportunity to suit up arrives on Dec. 6 in New England.
Mathews (concussion) has been ruled out for Thursday's game in Detroit.
Mathews has made little progress in his quest through the concussion protocol, leaving the Eagles to trust in DeMarco Murray, Darren Sproles, and, to a lesser extent, Kenjon Barner out of the backfield. His next chance to take the field arrives on Dec. 6 at New England.
Perhaps signaling concern with regard to Jones' Week 12 status, the Raiders promoted Jeremy Ross -- an option to fill in for Jones on kick returns -- from their practice squad in advance of Sunday's game against the Titans.
