TEMPE, Ariz. -- Carson Palmer is a man of his word.

Palmer walked to the podium outside the Arizona Cardinals' practice facility Monday for his weekly news conference wearing a No. 33 cardinal-red Stanford football jersey that teammate Stepfan Taylor wore in the 2011 Orange Bowl. Palmer lost a bet with Taylor when USC got trounced by Stanford in the Pac-12 championship game Saturday, 41-22.

Palmer said he had to wear the jersey until 5 p.m. Monday, when the bet would be paid off.

“I told Stepfan that there’s no way he could fit in this jersey anymore,” Palmer said. “He’s put on at least 25 pounds since he played."

Palmer won the 2002 Heisman Trophy at USC, where he set 21 school and conference records. Taylor played at Stanford from 2009-12, when he set the school record for rushing attempts, rushing yards, total touchdowns and 100-yard games.
