Clutching his right arm in pain late in the fourth quarter Sunday night, Ravens Pro Bowl outside linebacker Terrell Suggs made a beeline to the sideline toward team doctors and trainers.

The reigning NFL Defensive Player of the Year didn't return, heading to the locker room for further examination during the final minutes of the Ravens' 23-20 loss against the Pittsburgh Steelers at M&T Bank Stadium.

Although Suggs appeared to injure his biceps, the team made no announcement regarding the injury . Suggs is scheduled to be examined by a doctor Monday, while the team awaits more information on his status.

"No immediate word on Terrell Suggs," coach John Harbaugh said.

In the locker room afterward, Suggs' arm wasn't in a sling. He was careful not to use it much, though.

Suggs declined to get into specifics about his injury, only telling The Baltimore Sun: "I'll be all right."

If this injury sidelines Suggs, it would mark the second time this year he would have to battle back from injury. Suggs made it back from a partially torn right Achilles tendon sustained in late April that required surgery.

"We know he's a tough guy," nose guard Terrence Cody said. "To take an injury like that, it's real tough. If we don't have him next week, we have to step up as a defense. I don't know what happened, but I saw him coming off the field holding his arm."

Suggs' injury created concern among his teammates considering his importance to the defense in terms of skill and leadership.

"I saw him going off and I kind of shook my head," free safety Ed Reed said. "You hate to see that for anybody, but for Suggs to battle the way he did to get back and to have something like that. Hopefully, it's just minor. When I saw that, I hate to see him go down like that."

Should Suggs miss time with the arm injury, the Ravens would fill his spot with a combination of players. That would include outside linebackers Paul Kruger, Courtney Upshaw and Albert McClellan.

"We definitely don't want to lose any other players," Upshaw said. "A player like Suggs, his presence is a big thing for us."

Costly penalty

Outside linebacker Paul Kruger sacked Steelers quarterback Charlie Batch once, marking the fourth consecutive game the Ravens' leading pass rusher has had at least one sack.

However, that's not the play that will stick with Kruger from this game.

During the first play of the Steelers' game-winning drive, Batch's throw was completed to Mike Wallace as Kruger crashed into him late from behind and was flagged for roughing the passer. The 15-yard infraction gave the Steelers a first down at the Ravens' 19-yard line.

"I had a clear shot at him," Kruger said. "I just threw my hands too high and shouldn't have made it that close. It was a big mistake on my part for even making it a possible call, and I can't believe I put my teammates in that situation. There's not much to say."

Kruger said he disagreed with the call.

"I didn't think so, but I saw out of the corner of my eye the referee throw the flag," said Kruger, who leads the Ravens with 6.5 sacks. "I'm just disappointed in myself, and I can't put my teammates in that situation."
