Carr's struggles in the last two games highlighted how lost the Raiders will be without him.
The Oakland Raiders got shocking news Monday afternoon when it was discovered standout quarterback Derek Carr has a transverse process fracture in his back and will miss two to six weeks.
His injury could not have come at a worse time for the Raiders.
Del Rio said Carr, who suffered a broken leg in week 16 of last season and missed the play-offs, is sorry.
Raiders second-string quarterback EJ Manuel replaced Carr in the second half and completed 11-of-17 passes for 106 yards with one interception in the loss.

Similarly, Washington also urged neighbouring countries to "reject unilateral measures and the use of force". Kurds celebrate to show their support for the independence referendum in Duhok, Iraq, September 26, 2017.
Carr's season is not over, and the Raiders aren't rushing him back. But it's hard to imagine that Del Rio would embrace the idea, especially if he believes that Carr's injury status is temporary. Certainly the way EJ played (Sunday) was uplifting.
But, just one quarter of the way into this special season, the Raiders, and their quarterback, are decidedly not fine.
As such, Manuel will be under center in a really important Week 5 game against Baltimore this upcoming Sunday at the Coliseum. Oakland would lose consecutively a year ago, but that came in Week 17 to the Broncos and in the AFC Wild Card game on the road to the Houston Texans.
The week after that, they have another home game against the rival Chargers.
The Raiders have looked flat for most of the past two games.
There's no time too soon for Carr to return, but there's no obvious soft landing spot for him in October, either. The Ravens, also 2-2, don't seem to be a very good team.
