Joe Flacco downplayed the notion that his health is the root cause of his struggles.

Still, it’s hard not to notice his body language and his decreased mobility.

“I’m as close to 100 percent as I can be,” Flacco said. “I’ve got bruises and stuff like that, but it’s not affecting me out on the field. I didn’t feel anything out on Monday night.

“I stood back there and felt great physically. I felt like I was able to move around good, and I’ll continue to feel that way as long as our guys continue to do what they’re doing.”

For the season, Flacco has completed 63.3 percent of his throws for 2,881 yards, 14 touchdowns and 11 interceptions for an 84.6 passer rating.

Flacco acknowledged that defenses are disguising coverage schemes and making adjustments.

Ravens QB Joe Flacco (knee, hip) took reps Wednesday. Flacco is expected to start in a good matchup against the Lions.

Ravens QB Joe Flacco (ankle) took reps Friday.

Ravens QB Joe Flacco (ankle) practiced fully Thursday and said the ankle feels good. He should be fine to play Monday Night, but has been struggling to put up good fantasy numbers lately. He did throw for 289 and a TD last week after no TDs in his previous 3 games.

Joe Flacco says his ankle "feels great." The key is not aggravating it again.

Joe Flacco rolled his right ankle in third quarter of the Ravens' 20-17 win over the Steelers last night, and looked to be moving gingerly at times during the rest of the game.

The second-year quarterback initially injured the foot/ankle against the Vikings back on Oct. 18, and he appeared to aggravate the injury on a sack by Steelers linebacker LaMarr Woodley last night.

He had the ankle taped by team trainers and didn't miss any action, but it certainly looked like he was having trouble moving in the pocket down the stretch.

Flacco hasn't been at his best the last few weeks, missing on deep balls and struggling to find an overall rhythm in the passing game.

Head coach John Harbaugh said today that he isn't sure if the ankle injury has directly led to Flacco's recent drop in performance, but acknowledged that it might be something which is affecting his quarterback on gamedays.

"I think Joe's done a heck of a job of fighting through a bit of an ankle," Harbaugh said. "It's not a major injury, but I'm sure it's bothersome for a quarterback to have that foot a little bit sore.

I'm starting to wonder if that ankle injury quarterback Joe Flacco suffered a couple of weeks ago is more serious than he is letting on.

Ever since the injury, Flacco has been slow-moving in the pocket, and very seldom steps up into it when he gets pressure. A lot of his passes are now sailing because he isn't stepping into his throws. An ankle injury would cause faulty mechanics. In his brief time in Baltimore, Flacco has been very accurate, until lately.
