More than two dozen Colts players and staff shaved their heads this week in a show of support for head coach Chuck Pagano. Pagano is scheduled to start a second round of chemotherapy treatment this week as he fights leukemia.

Andrew Luck, Adam Vinatieri, Reggie Wayne, Robert Mathis, Antoine Bethea were among the players who went under the clippers.

Interim head coach Bruce Arians says Pagano will undergo a third round of chemo after this week's treatment, but they are still hoping he'll be on the sideline for the December 30 game against Houston.
