With Carr out, the Raiders are expected to turn to veteran backup EJ Manuel.
"It could be as short as two weeks - it could be longer", Del Rio said on Carr's timetable for return from his latest injury.
According to Vic Tafur of The Athletic, Carr could be out two to six weeks with a fracture in his back.
Carr remained on the ground for several moments as team trainers and medical personnel came on to the field to tend to him. Two weeks might be too many to be without Carr. In fact, the bone doesn't even need to heal to return to play.
Manuel will start Sunday's game versus the Ravens with Derek Carr (back) sidelined, Michael Gehlken of the Las Vegas Review-Journal reports. At 2-2, the Raiders have no cushion, and yet they're going to start a quarterback who hasn't won a start since September 2014.
As we wrote following the game yesterday, we hate seeing players get injured, and this couldn't have happened to a classier player in Carr, who signed a massive extension this offseason. He then moved the Raiders across midfield while seeking a late, go-ahead touchdown before throwing a game-sealing interception on a deep shot to Amari Cooper with 1:46 to play. Now, Del Rio said Carr will miss at least two games for Oakland. There is no planet where Manuel is considered an upgrade to Carr.
Del Rio was pleased with Manuel's performance. In a quarter of action against the Broncos he completed 11 of 17 passes for 106 yards with an interception.
Carr has embraced his role as leader of the Oakland Raiders, and has done an exceptional job, playing MVP caliber football for the most part when he is healthy and on the field.
Carr is likely to do the same and try to play missing only one game. (Specifically, Colin Kaepernick, but frankly there would have been a few that would have been an improvement).
