Indianapolis Colts coach Chuck Pagano, who is undergoing treatment for leukemia, attended Sunday's game against the visiting Miami Dolphins, according to ESPN.com.
Pagano has been on leave because of the illness. Doctors, however, assured Pagano that he is immune from infection.
He received added security as they escorted him to owner Jim Irsay's suite to watch the game. The Indianapolis Star reported that Pagano spoke to the team before the game.
Pagano will return to the hospital Monday for a second round of radical chemotherapy.
Pagano appeared at the Colts' facilities last Monday. It was the first time he was with the team since he was diagnosed with leukemia on Sept. 26.
