Claiborne (hamstring) has been ruled out for Sunday's game in Miami, Armando Salguero of the Miami Herald reports.
With Claiborne unavailable, Byron Jones figures to primarily work as a cornerback, which should free up some extra snaps for safeties Jeff Heath and J.J. Wilcox. Claiborne isn't particularly good, so his absence isn't cause to significantly downgrade the Dallas defense.
Romo will miss the remainder of the season after being diagnosed with a hairline fracture to his left clavicle Friday, Brandon George of The Dallas Morning News reports.
Romo's clavicle won't actually require surgery but he'll still need to sit out the rest of the season after sustaining the break during Thursday's loss to the Panthers. Matt Cassel will seemingly take over from here on out as the Cowboys fade out of playoff contention after Romo's second left clavicle injury in just a matter of months.
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.
