Allen Park — Calvin Johnson said Wednesday his ankle injury wasn't a concern, but it was bad enough to keep him out of Lions practice, the first one he's missed in 2014.

"I'm not concerned about it," the All-Pro receiver said Wednesday. "When those things happen, you just get in here and just work and work and work until those things get right."

Johnson suffered the injury in the second half of Sunday's win over the Green Bay Packers but he said he wasn't worried after the game.

Meanwhile, the Lions did receive some good injury news Wednesday as strong safety James Ihedigbo (neck) was a full participant in practice for the first time during the regular season. Ihedigbo has been dealing with a nerve injury since the second exhibition game and has been inactive the first three games while Isa Abdul-Quddus has started in his place.

If Ihedigbo can practice fully Thursday, there's a good chance he'll make his debut Sunday against the New York Jets.

Right tackle LaAdrian Waddle (calf) practiced for the first time since suffering his injury in Week 1 but was extremely limited during the portion open to the media. If he can't play, Cornelius Lucas or Garrett Reynolds will start at his position.

In addition to Johnson, cornerback Cassius Vaughn (ankle), safety Don Carey (hamstring) and linebacker Travis Lewis (quad) missed practice Wednesday. Vaughn and Lewis missed Sunday's game, and Carey left in the first quarter.

Special teams ace Montell Owens (hamstring) also returned to practice after being inactive for the last game but was limited. Defensive end Ezekiel Ansah (knee), defensive tackle Nick Fairley (biceps) and running back Joique Bell (knee) were limited, too.

Defensive end George Johnson (groin) was a full participant Wednesday.

Johnson missed several practices in 2013 as he dealt with knee and finger injuries, both of which he had surgically repaired in the offseason. He said it's important to practice as much as possible, but being healthy is obviously the top priority.

"The timing, that's the biggest thing," he said of practicing often. "Getting out here and doing things full speed so that (quarterback Matthew Stafford) can get a feel for it, and you can get a good feel for it as well and just build your confidence."

The Jets, meanwhile, had four starters miss practice Wednesday — defensive tackle Muhammad Wilkerson, wide receiver Eric Decker (hamstring), center Nick Mangold (shoulder) and cornerback Dee Milliner (quad).

Wide receiver David Nelson (illness) was out, right guard Willie Colon (calf) was limited and running back Chris Johnson (ankle) was a full participant.

New Lions kicker Alex Henery is wearing No. 5, and linebacker Josh Bynes is wearing No. 57.
