Detroit Lions wide receiver Calvin Johnson and Green Bay Packers quarterback Aaron Rodgers will not participate in the Pro Bowl later this month.
Tamba Bay Buccaneers wide receiver Vincent Jackson has been named to replace Johnson, who has an injury.
Rodgers said on his weekly radio show he won't play in the Pro Bowl because of multiple unspecified injuries, according to ESPNWisconsin.com.
"I didn't pass my physical," Rodgers said.
Also, Cincinnati Bengals offensive tackle Andrew Whitworth has been added to the AFC squad for the Pro Bowl, which will be played on Jan. 27 in Honolulu.
Whitworth will replace Denver's Ryan Clady, who will be unable to play because of an injury.
