Colts offensive coordinator Bruce Arians was hospitalized Sunday morning after falling ill. Clyde Christensen will call plays during Sunday’s wild-card game against the Ravens.

According to Mike Chappell of The Indianapolis Star, a Colts spokesman said Arians is “doing fine.” He missed Thursday’s practice with flu-like symptoms.

Arians was the team’s interim head coach for most of the season while Chuck Pagano received treatment for Leukemia. The Colts were 9-3 with Arians at the helm. 

Christensen is in his 11th season with the Colts and was the team’s offensive coordinator the past two seasons. He has been the quarterbacks coach this season.
