Orchard Park, N.Y. — James Ihedigbo sat out the Lions’ third exhibition against Jacksonville to rest, but after he skipped the trip to Buffalo on Thursday night, coach Jim Caldwell indicated the starting strong safety is dealing with some kind of ailment.

“We felt he could get treatment a little bit better at home than he could here, just keep him off the plane and just make sure he’s getting the treatment he needs,” Caldwell said after the Lions’ 23-0 victory.

The Lions have not said what body part is bothering Ihedigbo. After he sat last week’s game, he returned to practice, but was obviously not well enough to make the trip. He was one of 11 starters inactive, but the only one who didn’t travel.

Caldwell also didn’t provide much of an update on the two other players who didn’t travel, safety Don Carey and rookie outside linebacker Kyle Van Noy.

Van Noy underwent surgery Thursday for a core muscle injury and will miss the start of the regular season. The injury typically holds players out four to six weeks, but the Lions didn’t say how long the second-round pick would be out. Caldwell left open the possibility that Van Noy could receive the team’s short-term injured reserve designation, which would hold him out of the first eight games.

“I’m not certain what the prognosis will be,” Caldwell said. “I’m sure we’ll announce that in the next day or so after we’ve had a chance to discuss it thoroughly.”

Carey left last week’s game with a hamstring injury and missed practice all week. He was battling Isa Abdul-Quddus, who played great Thursday, and undrafted rookie Jerome Couplin for one of the final safety spots, so the timing couldn’t have been worse.

“It’s not something that’s going to keep him out forever. Let’s put it that way,” Caldwell said of Carey.

Rookie center Travis Swanson underwent X-rays after the game, but said it was for a finger sprain he was able to play through.

“It was something I just brought up to them at the end of the game, and they’re like, ‘You might as well just make sure,’ ” Swanson said.
