Injury roundup: Megatron (ankle) limited in practice

Calvin Johnsonis in London. Calvin Johnson is running in London. But Calvin Johnson is just barely practicing in London.

The Detroit Lions' star receiver was listed as limited Wednesday as he continues to attempt a comeback from his injured ankle.

It's not a shock that Megatron wasn't much of a participant in another practice. Whether or not he plays Sunday stems little from if he practices mid-week.

We would still be surprised if the wideout suited up Sunday against the Atlanta Falcons, as the Lions could try to buy two extra weeks of rest for Johnson -- with the bye week coming up -- instead of putting him in harms way at less than 100 percent and chancing a reaggravation of the injury.

Here are some other injuries we are following Wednesday:

1. Lions tight ends Eric Ebron (hamstring), Brandon Pettigrew (undisclosed) and Joseph Fauria (ankle) didn't practice. The team signed veteran Kellen Davis this week due to all the injuries at the position.

2. New York Giants linebacker Jon Beason (toe) says there is a "50-50" chance he's done for the season.

3. A dispatch from NFL Media's Steve Wyche from across the pond in London: Falcons receiver Harry Douglas, who has missed the past four games with a foot injury, won't practice today, according to Coach Mike Smith. However, Douglas will go through a rehab workout today to determine if he will practice the rest of the week and possibly play against the LionsSunday.

Falcons defensive lineman Jonathan Babineaux (ankle) will not practice Wednesday either, Smith said.

4. Robert Griffin III took first team reps during Redskins practice Wednesday. Griffin wasn't made available to the media, and coach Jay Gruden has already announced Colt McCoy will be the starting quarterback Sunday if Griffin isn't ready to go.

5. Bills safety Aaron Williams suffered a neck injury in Sunday's last-second win over the Vikings, but he was back on the practice field Wednesday.

6. Panthers running back DeAngelo Williamswas not in pads on Wednesday and was expected to work on the side during practice.

7. Vikings coach Mike Zimmer said John Sullivanpassed the first concussion protocol test and believes the center will be good to go Sunday.

8. Tampa Bay Buccaneers quarterback Josh McCown is expected to throw during practice Wednesday, but the Bucs will likely stick with current starter Mike Glennon for another week.

Rookie running back Charles Simswill officially return to practice Wednesday, but won't count against the roster until officially activated, which could come before next week's game against the Cleveland Browns.

9. Running back Jamaal Charles (concussion) and safety Eric Berry (ankle) were both clearedto participatein practice Wednesday for the Chiefs.

10. Packers cornerback Sam Shields (knee) and running back James Starks (ankle) did not participatein practice on Wednesday. Also missing practice were defensive end Datone Jones (ankle) and safety Morgan Burnett (undisclosed).

Leon Hall was also out with a back injury. Linebacker Vontaze Burfict (concussion) was suited up for practice and was a limited participant.

12. Jake Locker was limited in Wednesday's practice, and head coach Ken Whisenhunt said there will be more clarity on Locker's situation Thursday, per The Tennessean.

14. For the Chargers, Brandon Flowers has been ruled out with a concussion, while Jason Verrett (shoulder) was a limited participant all week and is listed as questionable. Per NFL Media Insider Ian Rapoport, there is a "very good chance" San Diego will be without Verrett against the Broncos on Thursday Night Football. The Chargerswill likely startRichard Marshall and Shareece Wright -- the same duo that started in last year's win over Denver -- according to Rapoport.

15. Alan Ball (biceps) and Andre Branch (groin) did not participate in Wednesday's practice with the Jaguars, though Toby Gerhart was back, per the Florida Times-Union.

16. Bill O'Brien said Jadeveon Clowney, who was limited Wednesday, is getting "better and better everyday" and will probably be a game-time decision. The coach sounded optimistic the team's No. 1 pick will play Sunday. Andre Johnson (ankle) was also limited, while Brian Cushing (knee) did not participate in practice, per the Houston Chronicle.

17. Ryan Shazier (MCL sprain) was a limited participant Wednesday, per USA Today. The Steelers rookie linebacker was a late scratch Monday night but could be back in game action Sunday against the Colts.
