Cowboys quarterback Jon Kitna missed a second straight day of practice with a strained muscle in his side, making it less likely he will play the season finale against the Eagles on Sunday.

Stephen McGee ran the first-team offense Thursday and would make his first career start Sunday at Lincoln Financial Field if Kitna isn't healthy.

Interim coach Jason Garrett said Kitna was "walking around OK," but the club would wait at least another day before making a decision on his availability.

Fine reduced for Jackson hit. The NFL has reduced the fine on Atlanta Falcons cornerback Dunta Robinson for his Week 6 helmet-to-helmet hit on Eagles receiver DeSean Jackson from $50,000 to $25,000, according to NFL.com.

Favre fails concussion test. The Minnesota Vikings want quarterback Brett Favre to give it one more try and start Sunday at Detroit, but by NFL concussion rules he first must be cleared by the team's medical staff.

Vikings interim coach Leslie Frazier said that Favre hasn't passed the first stage of the standard post-concussion testing. There's also a conditioning component to receiving clearance to return, if Favre can prove he's symptom-free and functioning normally again. Though he said he wouldn't rule out Favre, Frazier also said Saturday would probably be the "cutoff" for Favre to pass the tests.

The 41-year-old Favre has said this will be his last season.

Jaguars goes under knife. Jacksonville QB David Garrard had surgery on a torn ligament in his right middle finger.

NFL fines Jets for tripping. The NFL has fined the New York Jets $100,000 for violating league rules when assistant coach Sal Alosi tripped Miami's Nolan Carroll on the sideline during a punt return.

The Jets were fined Thursday because Alosi placed players in a prohibited area on the sideline to impede opposing team's special-teams players.
