The Colts are going to be without head coach Chuck Pagano for at least six weeks while he is treated for leukemia.  Pagano's illness was discovered last week when he went to the hospital for bruising.  The 52-year-old was named Colts coach in January and has led the team to a 1-and-2 record thus far.  Offensive coordinator Bruce Arians will take over as the team's interim head coach while Pagano is gone.
