BALTIMORE - Indianapolis Colts offensive coordinator Bruce Arians was hospitalized Sunday with an undisclosed illness, but the team expects him to make a quick recovery.

Arians missed the AFC wild-card game between the Colts and Baltimore Ravens. Quarterbacks coach Clyde Christensen called the plays in Arians' absence. The Colts lost the game, 24-9.

Arians, a York High graduate, served as interim coach for 12 games this season, going 9-3, when head coach Chuck Pagano was undergoing chemotherapy treatment for leukemia.

After the game, Pagano said Arians would remain hospitalized in Baltimore overnight for observation and likely rejoin the Colts in Indianapolis on Monday.

"Just precautionary," Pagano said. "I think every test they've done on Bruce came back negative. He's in good shape. ... He'll be back with us tomorrow."
