Source: Bruce Arians back in hospital

Indianapolis Colts offensive coordinator Bruce Arians returned to the hospital Tuesday in Indianapolis for treatment of an inner ear infection, according to a league source.

The source said Arians will be released Wednesday and will start confirming head coach interview dates Tuesday night.

Arians was admitted to a Baltimore hospital Sunday morning after complaining he felt ill at the team breakfast. Without Arians, quarterbacks coach Clyde Christensen called the plays in the 24-9 season-ending loss to the Ravens.

Arians returned to Indianapolis Monday night after being released following a 36-hour stay.

Team owner Jim Irsay told The Associated Press in a text message that Arians was accompanied by two team doctors, had been medicated and appeared to be on the mend.

"He was in good spirits (and) is trending (in) right direction," Irsay wrote.
