Manning developed the problem while dealing with another injury along the bottom of the foot from the Oct. 4 game against Kansas City.
The Giants were 4-0 after their win at Kansas City. Now they are 6-5 and Manning has struggled in recent weeks, even though his inflamed arch has healed.
He said Monday the injury doesn't bother him, and he doesn't think about it. He adds that this is something he's not "overly concerned with."
