Colts offensive co-ordinator Bruce Arians hospitalized with "undisclosed illness.''

BALTIMORE - Indianapolis Colts offensive co-ordinator Bruce Arians has been hospitalized Sunday with an undisclosed illness.

The team said he is doing well in a local hospital, and that Arians would not attend the AFC wild-card game between the Colts and Baltimore Ravens.

Quarterbacks coach Clyde Christensen will call the plays in Arians' absence.

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