Update: Bruce Arians says Carson Palmer broke his left arm in Cardinals’ shutout loss vs. Rams

Had the Arizona Cardinals beaten the Los Angeles Rams in London, the Seattle Seahawks would’ve had a chance to take sole possession of first-place in the NFC West. It’s currently 26-0 Rams in the third quarter, so we can forget about any hope of Arizona helping out the Seahawks.

Of greater long-term importance is the left arm injury sustained by Arizona quarterback Carson Palmer. Facing heavy pressure, Palmer threw an interception to Lamarcus Joyner after being hit hard by blitzing linebacker Alec Ogletree. He has officially been listed as out for the rest of the day.

Drew Stanton is Palmer’s backup and he’s already thrown an awful interception, and Arizona’s offensive success from last week has not translated across the pond this week.

Arizona plays a Thursday night home game against Seattle on November 9th, so it’s worth monitoring whether or not Palmer’s injury is serious enough for him to not play against the Seahawks.

Update: It’s bad news for the Cards.
