New photos show the severity of the injury to New York Giants defensive end Jason Pierre-Paul's right hand, clearly showing his index finger mostly missing and his thumb and middle finger also damaged.

The New York Daily News posted a photograph Thursday showing Pierre-Paul without a bandage over his hand. It appeared that almost all of his index finger was missing. Paul still had small bandages on his thumb and middle finger. Part of his thumb appeared to be missing.

The two-time Pro Bowler missed all of training camp after the Fourth of July fireworks accident. He allowed the team to examine his injured hand earlier in September, and the Giants declared that he wasn't ready to play. He remains unsigned and is not being paid.

Bulaga injured

Packers right tackle Bryan Bulaga left Thursday's practice after injuring his left knee and his status for this weekend's game against the Seattle Seahawks was unclear.

Bulaga has suffered season-ending injuries in both 2012 and 2013.

"It sounded like his foot kind of got caught up when they were doing some drills or something," Pro Bowl left guard Josh Sitton said. "I didn't see it. I wasn't over there with him."

If Bulaga's knee injury is serious enough that he won't be able to play in Sunday night's home game, fourth-year man Don Barclay would start in his place. Barclay confirmed that he took over at right tackle with the starting offensive line after Bulaga departed.

Barclay struggled during preseason but spent much of his time at left tackle.

"I feel prepared," Barclay said. "The coaches have done a good job of giving me reps all over the board, both tackles and guard. I feel fine."
