Patriots' starting linebacker Rosevelt Colvin and backup cornerback Randall Gay were injured and not on the field in the fourth quarter of New England's 31-28 win over the Philadelphia Eagles on Sunday night. The Patriots said Colvin did not return because of a foot injury. They said Gay had a back injury. The unbeaten Patriots were having one of their worst defensive games of the season as the team matched its season high by allowing 28 points.
