John Kuhn

With the opening of training camp set for July 26, Dover High School graduate John Kuhn is reportedly battling a nagging right knee injury.

The Green Bay fullback hurt the knee in the Packers' 37-20 playoff loss to the New York Giants on Jan. 15. According to ProFootballTalk.com, the injury was first thought to be a mild medial collateral ligament (MCL) sprain that wasn't considered very serious.

But Kuhn has told FoxSportsWisconsin that he's been working hard in the offseason to make the knee stronger, but he's still not sure if he'll be ready for training camp.

"Those decisions aren't up to myself," Kuhn told FoxSportsWisconsin. "I anticipate being able to do some work, but I'm not exactly sure what that's going to be. It will be something on the field, but I'm just not sure how many active plays it will include. I feel healthy enough. But sometimes you feel healthy enough and coaches and doctors want to be cautious. We'll see."

The 6-foot, 250-pounder did not go into any more specifics about the injury.

Kuhn was named to the 2012 Pro Bowl and was recently listed at No. 92 among the top 100 players in the NFL. The NFL Network conducted the ranking, based on a survey of NFL players.

Last season, Kuhn rushed 30 times for 78 yards (2.6 yards-per-carry average). He also had 15 receptions for 77 yards (5.1 yards-per-catch average). He scored six total touchdowns.

His most productive season came in 2010, when he rushed 84 times for 281 yards (3.3 per carry) and caught 15 passes for 97 yards (6.5 per catch). He had six TDs in that season, as well. Kuhn helped the Packers win the 2011 Super Bowl.

Kuhn is entering his seventh season in the NFL.
