OWINGS MILLS, Md. -- Baltimore Ravens trainer Mark Smith told coach John Harbaugh on Monday that he had good news and more good news.

"We won the game, and nobody's getting an MRI today," Smith told Harbaugh.

This marked the first time all season (15 games) that the Ravens haven't had a significant injury to report after the game. Baltimore currently leads the NFL with 19 players on injured reserve, including eight starters: quarterback Joe Flacco, wide receiver Steve Smith Sr., linebacker Terrell Suggs, running back Justin Forsett, offensive tackle Eugene Monroe, center Jeremy Zuttah, defensive end Chris Canty and tight end Crockett Gillmore.

What makes this more surprising is that the Ravens came out unscathed after a hard-hitting rivalry game against the Pittsburgh Steelers.

"It's probably pretty rare," Harbaugh said.

Harbaugh did provide two injury-related news. Left tackle Eugene Monroe had shoulder surgery, and reserve wide receiver Marlon Brown isn't expected to play this season.

Monroe, who is on injured reserve, had a labrum tear repaired. This isn't expected to affect his offseason workouts.

"I think it's a pretty quick recovery," Harbaugh said. "It shouldn't be an issue."

Brown has been inactive for the past five games with a back injury. He's been dealing with back spams and a disk issue.

"About two weeks ago, I could just tell he wasn't going to get back, so I kind of gave up hope and I think he did, too," Harbaugh said. "I'm not sure why Ozzie [Newsome, general manager] didn't put him on IR."
