The Green Bay Packers saw three more starters exit Sunday's loss to the Detroit Lions, but a fourth who didn't play -- defensive end Cullen Jenkins -- could be out for the season, the Milwaukee Journal-Sentinel reported Monday.
Jenkins, who has a calf injury that kept him out of practice last week, told reporters after Sunday's 7-3 loss in Detroit that the muscle pull he sustained Dec. 5 vs. San Francisco is the worst one he's had.
"There's been a few times I've done it this year going back to training camp," said Jenkins, who has a career-high seven sacks this season. "This is the worse one yet.
"It was a freak thing. I was trying to call off a game between me and (linebacker Frank) Zombo at the last minute because I recognized what the offense (was doing). I was getting ready to get back in my stance and they snapped the ball. I wasn't quite set, so I took a step back to go forward, and it got it."
Jenkins said no there is no timetable for a return and it is possible it will be a season-ending injury.
"You can't rule out any possibility right now," Jenkins said. "I have to take it week by week and see how it goes."
Zombo, who left the game during the fourth quarter due to knee tightness, said his exit was precautionary.
Colledge injured his left knee on the Packers' second play from scrimmage, trying to make a tackle after a fumble.
"I don't feel like it's going to be terrible, but it doesn't feel good right now," Colledge said. "It's too hard to judge."
