The Ravens issued the following statement about the NFL looking into Reed's status: "We are aware that they are reviewing practice and game video."
What can the Ravens expect if the NFL finds that the defending AFC North champions violated procedures on reporting injuries?
The league fined the Buffalo Bills and Washington Redskins $20,000 apiece Friday for how it handled situations involving defensive end Mario Williams and quarterback Robert Griffin III, respectively.
The Redskins were fined for not properly updating the media on Griffin's status after he suffered a mild concussion with coach Mike Shanahan saying only that Griffin was "shaken up."
The Bills didn't list Williams' sprained left wrist. Like Reed, the NFL learned of the injury once Williams complained of the ailment publicly in interviews.
Meanwhile, Ravens coach John Harbaugh weighed in on the Reed situation Friday.
"We have probably 25 of 30 guys that have things like that, things that they can play through that don't cost them any time, practice-wise or game-wise," Harbaugh said. "I know what the players in this league do physically is something I know I admire and I think everybody should admire.
"It's a tough game, it's a physical sport. What he's talking about are the things that all these guys have. There are always a lot of bumps and bruises, and nicks and tears, if you will, that guys have to deal with."
When asked why he hasn't been on the injury report other than a hamstring injury before the Philadelphia Eagles game, Reed replied: "I don't know why it doesn't go on. I'm sure a lot of guys have been through this league and had injuries and it's not reported. That's the physical part of the game and a part of the game that the fans and y'all don't anything about. That's the part that we have to deal with from a worker's compensation situation, so to say. That's stuff that will be taken care of. I'm physically all right, but it is what it is on that."
Reed essentially dared the Houston Texans to go after his shoulder.
"Target it, target me, throw it, c'mon," Reed said. "Either way it goes, I'm on the field, I have to do my job and they know that whether I'm injured or not. I have had some shoulder stuff going on for a couple of years. It's nothing I can't play around or adapt my game to."
