Injury roundup: Reggie Bush (ankle) misses practice

Calvin Johnson isn't the only Lions weapon in question for Sunday's tilt in London.

Running back Reggie Bush sat out Thursday's practice with an ankle injury after seeing limited work on Wednesday, the team announced

It's a concerning downgrade for Bush, who told WXYT-FM before practice that he's "going to do everything (he) can to be out there on the field Sunday" after sitting out much of the second half of last week's win over the Saints. With just four rushes for 10 yards, Bush lacked his usual explosiveness against New Orleans.

If Bush can't go, look for a heavy serving of Joique Bell on the ground with a side helping of Theo Riddick. No matter who plays, Detroit's struggling offense has an outstanding chance to get well against a Falcons defense allowing the second-most yards per play in the NFL.

Other injuries we're tracking on this fine Thursday:

1. Back to Megatron, who wore his helmet and was seen "cutting and running routes" during practice, per the team, who designated him as limited. With the wideout's sprained right ankle on the mend, there's still a chance he suits up against Atlanta.

2. Also for the Lions, tight ends Joseph Fauria (ankle), Eric Ebron (hamstring) and Brandon Pettigrew (undisclosed) were not on the practice field, the team announced. Detroit did welcome Ziggy Ansah (shoulder) back after the pass rusher sat out Wednesday's session.

3. Atlanta Falcons wide receiver Julio Jones (ankle) participated fully in Thursday's practice. Meanwhile, pass rusher Jonathan Babineaux (foot) continued to be held out and pass-catcher Harry Douglas (foot) was limited, according to NFL Media's Steve Wyche.

4. Dallas Cowboys coach Jason Garrett said that quarterback Tony Romo (ribs/ankle) was present for walk-throughs, NFL Media's Desmond Purnell reported. The signal-caller did not participate in practice. Also for the Cowboys: defensive end Anthony Spencer (knee/foot) was limited in practice Thursday.

5. Philadelphia Eagles coach Chip Kelly told reporters in his Thursday news conference that linebacker Mychal Kendricks has been running around. Kendricks was a limited participant in practice.

6. Reggie Wayne (elbow) did not participate in Colts practice Thursday. The wideout watched from the sidelines, per The Indianapolis Star.

7. Owen Daniels (knee) and Chris Canty (wrist) were missing from Ravens practice Thursday. Daryl Smith and Steve Smith were also not present, though for non-injury reasons. Meanwhile, Eugene Monroe and Kelechi Osemele were both full participants for the second straight day after dealing with knee injuries.

8. At Packers practice, James Starks (ankle) and Datone Jones (ankle) returned, while Morgan Burnett (calf) and Sam Shields (knee) remained out.

9. Eric Decker and Willie Colon were all limited participants in Thursday's practice for the Jets. Meanwhile, Chris Johnson was a full participant.

10. Fozzy Whittaker (thigh) and DeAngelo Williams (ankle) did not practice for the Panthers. Williams has missed three straight games thus far this season.

11. Bears cornerback Kyle Fuller (hip/hand) was a limited participant at practice Thursday. Coach Marc Trestman said that Fuller "moved around well," according to ESPN.

12. A.J. Green did not participate in practice Thursday as he deals with a toe injury.

13. Josh McCown was a limited participant after returning to practice earlier in the week.

14. Pierre Thomas (shoulder) and Khiry Robinson (forearm) both missed Saints practice Thursday.

15. Toby Gerhart was a full participant in the Jaguars' Thursday practice as he works his way back from a foot injury. He appears ready to play Sunday. Dwayne Gratz was limited with a hip flexor.

16. Cardinals defensive end Calais Campbell was limited in practice. It was his first session since injuring his knee in Week 5.

17. Robert Griffin III was a limited participant in the Redskins' practice. The signal-caller took part in individual drills and team reps Wednesday as he works back from a dislocated ankle.

Also for the Redskins: Trent Williams (knee) and Ryan Clark (ankle/shoulder) were limited participants as well, while Alfred Morris (ankle) was a full go.

18. Shonn Greene (hamstring) was limited in Thursday's practice with the Titans. The running back, who has missed the last two games, said that he "did pretty much everything" and felt like he "would be able to (return Sunday), per The Tennessean.

19. Jason Verrett (shoulder) was declared active for the Chargers' Thursday night matchup against the Broncos. However, he exited during the first half with the same injury and is questionable to return.

20. Chris Owens (knee) did not practice Thursday for the Chiefs, and wide receiver Donnie Avery (groin) has been ruled out when the team faces the Rams.
