The Indianapolis Colts come into the season opener with a proven quarterback, a playoff pedigree and the home-field advantage over the Oakland Raiders.

The Raiders are hoping the element of surprise will be enough to overcome those hurdles.

Coach Dennis Allen is refusing to name his starting quarterback for "competitive" reasons even though all signs point to Terrelle Pryor getting that call over Matt Flynn on Sunday in Indianapolis.

The San Francisco Chronicle and NFL.com reported Monday that Pryor would start. He has opened practice with the first-team offense this week and has been getting plenty of work with the starters in a clear sign that he will be the No. 1 quarterback Sunday.
