Colts owner Jim Irsay confirmed on Monday morning that head coach Chuck Pagano is hospitalized with leukemia, but Irsay said the cancer is treatable and that everyone is optimistic. “It’s been a very difficult week,” Irsay said. “The coach was feeling some fatigue over the last two weeks, had noticed some bruising on his body that at first he thought could have been from contact on the field, coaching, or playing with his grandkids or whatever, and eventually through talking to his wife, Tina, she said, ‘You need to check that out.’”
