Ravens star running back Ray Rice suffered a strained left hip flexor Sunday during the fourth quarter of a 14-6 win over the Cleveland Browns, a potential setback for the offense.

Although the injury initially appeared serious as trainers attended to him on the field, Rice walked off the field under his own power. However, the Pro Bowl runner didn't return. Rice wasn't on crutches after the game and wasn't limping badly.

The Ravens are hopeful that the injury isn't going to sideline Rice long and he's not scheduled for a magnetic resonance imaging exam.

“We’re confident and optimistic right now,” Ravens coach John Harbaugh said. “We’ll have to see how he responds.”

With Rice out of the game after rushing for 36 yards on 13 carries and losing one fumble, Bernard Pierce replaced him as the primary tailback and finished with a team-high 57 rushing yards on 19 carries with one touchdown run.

“The running game will keep rolling,” fullback Vonta Leach said. “Bernard did a good job for us and we've got confidence in Bernard just like we do with Ray. Hopefully, it's not that bad. I think we'll be all right.”

Once Rice left the game, Pierce helped the Ravens run out the clock with 21 yards on six carries during a late fourth-quarter drive.

“It was a long fourth quarter, and somebody had to grind out those runs,” Pierce said. “I've just got to keep playing to the best of my ability and keep making plays.

“As long as they keep giving me the ball, I'll keep carrying it. When you're trying to run the clock down, they know you're running. They have to stop you, and we can't let that happen.”

Pierce expressed confidence that Rice won't be sidelined long.

“Sooner or later, he's going to be back,” Pierce said. “Ray's going to be back, I have no doubt in my mind. ..

"I was right next to him and my first reaction was, ‘Get up.’ Once I saw he was getting up, I know, it’s going to be on me now. I just had to take the rest of the carries and hopefully finish the game strong."

In other injury news, rookie linebacker Arthur Brown hurt his left pectoral and didn't return and cornerback Chykie Brown hurt his right knee. Both will undergo MRIs on Monday.

Starting defensive lineman Chris Canty strained his groin and didn't return.

“I don't think it's a big deal,” Canty said. “It's just kind of a situation I got banged up and it was smarter not to go back in.”

Tucker misses twice, Cundiff perfect

Ravens kicker Justin Tucker and Billy Cundiff were on opposite ends of the kicking spectrum Sunday.

Tucker uncharacteristically missed both of his field goal attempts, misfiring wide right from 50 yards and 44 yards.

“With any kicker, eventually you're going to miss unfortunately,” Tucker said. “On the second ball, I actually felt like I hit it really well. I saw it on the Jumbotron, I liked what I saw. Maybe I misplayed the wind a little bit.”

Beaten out by Tucker last year for the Ravens' kicking job, Cundiff connected on field goals from 21 yards and 51 yards while being booed by a home crowd that hasn't forgotten or forgiven his pivotal missed chip shot in an AFC championship loss to the New England Patriots.
