Branch (ankle) is questionable to return to Thursday's game against the Cowboys.

The safety injured his ankle in the second half and had to be carted to the locker room. Branch recorded six tackles (three solo) and a fumble recovery before exiting. Detroit is already down Kerby Joseph (knee) and Thomas Harper (concussion) at safety, leaving Daniel Harper as the only healthy option.

Lamb has entered concussion protocol and been ruled out for the rest of Thursday's game against the Lions, Greg Auman of Fox Sports reports.

Lamb hit his head and shoulder hard after making a leaping attempt for a reception in the end zone early in the third quarter. He was briefly evaluated in the medical tent before heading to the locker room, and he was quickly ruled out from there. Prior to his exit, Lamb had six receptions (on eight targets) for 121 yards.

Lamb was escorted off the field by trainers and into the medical tent for further evaluation during Thursday's game against the Lions, Todd Archer of ESPN.com reports.

Lamb went up for a jump ball in the end zone early in the third quarter and came down hard on his head and shoulder. The exact nature of the injury is unclear, though he's likely being evaluated for a concussion at a minimum. After spending a brief time in the medical tent, Lamb walked to the locker room.

Brandel (concussion) was a full participant in practice Thursday.

It's not clear if Brandel has officially cleared concussion protocol, but he's certainly trending in the right direction with his full practice session Thursday. He was said to be symptom-free as of Monday, though he logged a limited practice session Wednesday. Ultimately, Brandel should suit up Sunday against Washington as long as he has indeed cleared protocol by then.

Jackson (ankle) was a limited participant in practice Thursday.

Jackson injured his ankle against Green Bay in Week 12 and missed this past Sunday's matchup against Seattle. He didn't practice to begin this week of prep, but a limited session Thursday improves his outlook for Sunday's game against Washington. Still, Jackson will probably enter the weekend with an injury designation if he isn't able to upgrade to full participation Friday.

Johnson (foot) did not participate in practice Thursday.

Johnson has missed the last two games after suffering the Lisfranc sprain in Week 11. He was originally expected to miss four-to-six weeks, and he does not appear on track to make an early comeback at this point. Fred Johnson should start in his place again if he can't go Monday against the Chargers.

Kelly (hip) was a full participant in Thursday's practice.

Kelly hurt his hip against Seattle on Sunday and began this week with a limited practice session. However, his ability to upgrade to full participation Thursday likely means he'll be good to go for this Sunday's clash against the Commanders. If that's indeed the case, Kelly should start at center, as usual.

Lindstrom (foot) was a limited participant at practice Thursday, Tori McElhaney of the Falcons' official website reports.

Lindstrom was added to the injury report Thursday as he continues to nurse the foot injury that's bothered him for the last month. The offensive lineman has yet to miss a contest this year, so he'll likely operate in his typical starting role at right guard again Sunday versus Seattle.

Epps (shoulder) was a full participant in practice Thursday.

The safety was designated to return from injured reserve two days ago, opening his practice window. Now that he's able to practice, Epps might have a chance to play Monday night against the Chargers. Epps logged 15 defensive snaps and 119 special-teams snaps before suffering the injury in Week 8.

Darrisaw did not participate in practice Thursday due to a knee issue.

Darrisaw did not play in this past Sunday's loss to Seattle due to a foot injury, but he was able to log a full practice session to begin this week of prep. However, he's now listed with a knee issue that caused him to be sidelined entirely Thursday. Darrisaw underwent knee surgery last November and has frequently appeared on the injury report this season for maintenance of the issue, so that could be the reason for his DNP again this week.
