The Philadelphia Eagles' quarterback, Donovan McNabb, will miss the rest of the season after rupturing the anterior cruciate ligament in his right knee during his side's surprise 31-13 defeat against the lowly Tennessee Titans.
McNabb was injured after a hit by the Titans defender Kyle Vanden Bosch. "An injury like that is usually eight months to a year, so he's done for the season," the Philadelphia head coach Andy Reid said.
The extent of the injury was confirmed late on Sunday night, leaving Vanden Bosch full of remorse. "I really feel bad for him," he said. "I never play with the intent to get anybody hurt. My thoughts and prayers go out to him."
McNabb was not the only high-profile casualty of the weekend's action. The Oakland Raiders lost their running back, LaMont Jordan, to a season-ending knee injury during their 17-13 defeat in Kansas City. The Green Bay quarterback Brett Favre also faces an uncertain future after being forced from the field with an elbow problem during his side's 35-0 defeat against the New England Patriots.
Favre has started 251 consecutive games since 1992, an all-time National Football League record, but may not be fit for next Sunday.
