Ravens quarterback Joe Flacco is practicing for the second consecutive day Thursday after suffering a low-grade sprained medial collateral ligament in his left knee Monday night against the Detroit Lions.
Flacco is wearing a protective brace on his left knee this week in practice and will do so Sunday against the New England Patriots. He was limited both Wednesday and Thursday.
It's unclear what kind of mobility Flacco has. He threw only from a stationary position during the portion of practice open to reporters.
Flacco isn't limping noticeably, and it remains to be seen if he'll choose to scramble much against the Patriots.
On Wednesday, Flacco said he last wore a brace on his left knee when he sprained his MCL during his junior year at Delaware.
"It has been pretty stiff," Flacco said."It's feeling better, though. It looks like it's getting better and better. Hopefully, some of the swelling will go down and stuff like that. So, yes, it's getting better. That's a good sign I think."
Running back Ray Rice, who has a relatively minor quadriceps injury, returned to practice on a limited basis. Rice appeared to be in pain at the end of his 19-yard run against the Lions
"I felt better every day," Rice said. "It's not bad at all. Trust me, I would know if it's bad. I wouldn't have went out and practiced. I'm smart enough, it's late in the year, to take care of things. I did what I had to do. I could have got more yards, but you be respectable in the situation and take care of yourself. No alarming threats."
Tight end Dallas Clark returned to practice after missing Wednesday with an illness.
Reserve cornerback Asa Jackson (hamstring) and linebacker Albert McClellan (neck) aren't practicing again. Jackson wasn't limping as badly Thursday.
"Everything is good, I'm going to be all right," Jackson said. "It's just one of those things. I had the same problem last year in the playoffs. I'm just trying to get my legs right.
"It's a lot of running and a lot of pounding on your legs. I'm just trying to get the swelling out. There's most definitely a chance for Sunday. We'll see how it goes later in the week."
Meanwhile, New England Patriots offensive tackle Nate Solder returned to practice on a limited basis following a concussion.
Rookie wide receiver Josh Boyce (ankle) didn't practice.
Besides Solder, several other Patriots were limited. That included quarterback Tom Brady (right shoulder), wide receivers Danny Amendola,(groin), Aaron Dobson (foot) and Kenbrell Thompkins (hip), cornerbacks Aqib Talib (hip), Alfonzo Dennard (knee, shoulder) and Kyle Arrington (groin), safety Steve Gregory (finger), tight end Michael Hoomanawanui (knee), offensive tackle Marcus Cannon (ankle), offensive tackle Will Svitek (ankle) and linebackers Brandon Spikes (knee) and Dane Fletcher (groin).
