Suggs has upper arm injury, Harbaugh talks handshake (torn biceps for Suggs)

Although the Ravens escaped Sunday's 23-20 loss to the Steelers mostly unscathed outside of the win-loss department, they have one major player whose health is a concern.

Linebacker Terrell Suggs suffered an injury to his upper right arm, coach John Harbaugh told reporters Monday, and the team doesn't yet know the extent of it. Suggs has already endured one long-term injury this season, missing the first six games following surgery to repair a torn Achilles tendon.

So that could be a big blow if it costs him more time.

"We've got an idea of what it is. It needs to be evaluated as far as coming back and possibly playing this week or not going forward," Harbaugh told reporters. "We'll just have to see where that is, and we should know something by tomorrow or Wednesday at the latest."

Harbaugh said the Ravens are encouraged that the injury might not be a long-term one.

"I think we are," he told reporters. "We are encouraged that it may not be, and we'll just have to see. If I knew that for sure or could say it for sure, I would. I just can't right now. But we have some encouragement there."

Harbaugh shared updates on other injured Ravens, saying he expects linebacker Dannell Ellerbe, who missed Sunday's game with injuries to his ankle, knee and finger, to have a chance to return this week against the Redskins.

"We were hopeful for this past game, but it just didn't work out," Harbaugh said. "We took him right to gameday, and he was unable to go."

Tight end Ed Dickson, who sat out the Steelers game with a hyperextended knee, did some running Monday and Harbaugh said he also has a chance to play this Sunday.

Harbaugh reported that cornerback Jimmy Smith, who hasn't played since Nov. 4 because of sports hernia surgery, continues to improve and will be "moving around a little" this week.

Linebacker Ray Lewis remains in Owings Mills rehabbing, but there's no news about whether he'll return this season.

Harbaugh also addressed the awkward postgame handshake with Steelers coach Mike Tomlin. Harbaugh was caught on camera trying to pull Tomlin back toward him after the Steelers coach tried to escape with a quick greeting. Harbaugh was then seen staring down Tomlin as he walked off the field.

"(It was) nothing uncomfortable at all," Harbaugh told reporters. "I thought Mike did a terrific job preparing his team. Obviously, they played very well, and I made a point to congratulate him on that. Hopefully he accepted that, and it was all good.

"I felt fine about it. It was fine. I just wanted to make sure he knew that we congratulated him and that was it."

Update: ESPN's Adam Schefter is reporting that Suggs has torn biceps and it's possibly an injury the linebacker can play through.

Suggs tweeted he'll be getting a second opinion. This could be bad or the Ravens star could be toughing this one out.
