BALTIMORE - Ravens outside linebacker Terrell Suggs left the field with a right arm injury late in the fourth quarter of Sunday's loss to the Steelers and didn't return to the game.
Suggs walked off the field holding in the area of his right biceps. He was tended to by Baltimore's medical staff before heading to the locker room for further examination.
Ravens coach John Harbaugh said after the game that the severity of Suggs' injury wasn't immediately known.
Suggs declined to comment on the injury following the game, merely announcing that he'll "be all right" as he walked out of the team's locker room, but teammates expressed concern when asked about Suggs' injury.
"He's a tough guy," Baltimore defensive tackle Terrence Cody said. "For him 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 really know what happened, but I saw him walking off the field holding his arm."
Suggs has played in each of the last six games after returning from the partial tear of his right Achilles tendon that he suffered in early May.
He had two tackles prior to exiting Sunday, including one for a loss.
"I don't know everything that's wrong with [his arm]," Ravens safety Ed Reed said, "but I saw him going off and I kind of shook my head. You hate to see that for anybody. But for Suggs to battle the way he did to get back [from the Achilles injury], and to have something like this, hopefully it's just minor.
"But when I saw it, I was like 'Ugh.' I hate to see him go down like that."
HOME WINNING STREAK SNAPPED: Sunday's loss snapped the Ravens' streak of 16 consecutive wins in games at M&T Bank Stadium (including one playoff game).
Prior to Sunday, Baltimore hadn't lost at home since Dec. 5, 2010.
The loss also snapped the Ravens' stretch of 12 straight wins against AFC North opponents, which was tied for the longest winning streak for a team against its own division since division realignment in 2002.
RARE BLOWN LEAD: Baltimore led 20-13 at the end of the third quarter Sunday, but Steelers quarterback Charlie Batch threw a game-tying touchdown pass to Heath Miller early in the fourth quarter before guiding a game-winning drive late that ended in Shaun Suisham's decisive field goal as time expired.
The loss was the Ravens' first this season when leading after the third quarter and just the eighth for the team since Harbaugh took over as head coach in 2008.
Baltimore is now 48-8 under Harbaugh when holding a lead after the third quarter, including 7-1 this season.
BIG DAY FOR BATCH: Starting in place of injured starter Ben Roethlisberger, as well as injured backup Byron Leftwich, Batch finished 25-of-36 for 276 yards with one touchdown and one interception.
He engineered three second half scoring drives, including the two in the fourth quarter.
The veteran Batch was starting just his ninth game since 2002 and the yardage represented his largest output since 2001.
MOVING ON UP: With his 34-yard third quarter scoring run Sunday, Ravens running back Ray Rice passed Willis McGahee for the second-most rushing touchdowns in team history.
Rice's score Sunday was his 32nd rushing score since being drafted by Baltimore in 2008.
Jamal Lewis ranks first in team history with 45 rushing touchdowns.
