ALLEN PARK -- The Detroit Lions appear to have dodged yet another injury scare.

Just one day after heading to the locker room with an apparent leg injury, center Graham Glasgow dressed for Detroit's joint practice with the New York Giants on Wednesday. He didn't do much and was held out of all intersquad work with New York, but his appearance in pads is an optimistic sign that whatever ails him is not serious.

This is at least the third prominent offensive player to sidestep major injury, including running back LeGarrette Blount and receiver Marvin Jones, both of whom left practices before returning a day later.

Glasgow is expected to become Detroit's full-time center this season, a position he's played only as an injury replacement in the past. He split his time between guard and center last year, and did so without missing a single snap all season.

The Lions were so impressed by his performance, his toughness, his attitude, that they let Travis Swanson walk in free agency and installed Glasgow as the full-time center. First-round pick Frank Ragnow, a center for most of his time at Arkansas, has moved to left guard.

With Glasgow sitting out most of Wednesday's practice, Ragnow was moved inside and got his first center reps of training camp. Wesley Johnson also got some time there.

Ragnow said he was told when he arrived at the facility in the morning that he'd be getting in some work at his old position. He said he felt like he did OK, though noted there was an adjustment period.

"I wouldn't say it's like riding a bike," he said. "It's a whole different league, whole different plays and everything. But it was good to be back. I'm just going to do whatever coach (Jeff) Davidson, coach (Matt) Patricia want me to do. I'm going to step up there and try to be the best at it."

The Lions have been reluctant to talk about their plan for Ragnow. They declined to say which position he'd play after taking him 20th overall in the draft. He was at left guard during portions of OTAs open to reporters, but the team insisted he'd play multiple positions, even though he continued to remain at left guard.

All the evidence suggests the Lions prefer Ragnow at left guard and Glasgow at center, though positional versatility is a key to overcoming injuries up front, which the Lions know all about after taking so many blows last season. And they used the Glasgow injury as an opportunity to begin preparing a contingency plan for the season.

"I think versatility is very important, yeah," Ragnow said. "Especially as someone who has not established himself in this league. I think the more you can do, the more you can help and the longer you're going to last."

Sticking to his injury policy, Patricia declined to elaborate on Glasgow's status. But his appearance suggests his absence won't be long.

"That's great (he was out there), and definitely what our unit wants," Ragnow said. "I mean, that's a tough guy. I've only known him for so long, but he's already established to me he's a tough guy. Up front, that's what we're looking for. So it's great to see that he's all right."
