Indianapolis Colts offensive coordinator Bruce Arians was discharged from an Indianapolis hospital on Wednesday night after receiving treatment for an inner-ear infection, a league source told ESPN.
Arians, who missed Sunday's loss to the Ravens and spent the night in a Baltimore hospital, is expected to interview for NFL head coaching vacancies.
The Philadelphia Eagles also have received permission to interview Arians, a league source said.
Arians was hospitalized 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 on Monday night after being released after a 36-hour stay.
Colts 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.
