Indianapolis Colts offensive coordinator Bruce Arians remained in a Baltimore hospital on Monday, although head coach Chuck Pagano said the team expected him back soon.
"All the tests, like I said (Sunday) night, every test that they ran on Bruce, and obviously they put him through a battery of tests, A to Z as they would do any of us, all have been negative," Pagano said. "So he's doing well."
Doctors were working to stabilize Arians' blood pressure before releasing him.
Arians was hospitalized Sunday because of an undisclosed illness and missed the Colts' AFC wild-card loss to the Baltimore Ravens. Quarterbacks coach Clyde Christensen filled in for Arians.
Arians had flu-like symptoms during the week but went to the hospital Sunday morning after reportedly feeling dizzy.
Arians served as the Colts' interim coach when Pagano was diagnosed with leukemia in late September. The Colts went 9-3 under Arians.
Arians has drawn interest from the Chicago Bears and Philadelphia Eagles as a head coaching candidate.
"We do not want to lose Bruce. He is so valuable to this organization and what he means to this organization and what he's done," Pagano said. "You want the best for Bruce. I want the best for Bruce. I want the best for his family. I want him to achieve and reach any goals that he has for himself throughout his coaching years, things like that.
"It's a hard spot but again we will cross that bridge when we come to it. Again, people are going to go after good people and this is just a byproduct of the success that we've had here."
