Oakland Raiders quarterback Carson Palmer will miss Sunday's season finale against the San Diego Chargers because of cracked ribs and a bruised lung.
Raiders coach Dennis Allen made the announcement to reporters on Monday.
Palmer left the first quarter of Sunday's 17-6 loss to the Carolina Panthers after taking a hit to the back by defensive end Greg Hardy.
Allen did not announce who will start in place of Palmer, who spent Sunday night in a hospital. Matt Leinart replaced Palmer against the Panthers. Terrelle Pryor is also an option.
NFL.com speculated that Palmer may have played his final game as a Raider. He is due to make $13 million next year and will be 33 years old. The Raiders (4-11) are in rebuilding mode.
