A team spokesman says all the tests on Arians came back negative, and doctors wanted him to stay until his blood pressure stabilized. Players say they were told the same thing during their final team meeting of the season Monday morning.
Indy has already given Arians permission to interview for head-coaching jobs with the Chicago Bears and Philadelphia Eagles. Rapoport has learned that the Cleveland Browns have put in a request as well, and the interview could take place this week.
