BALTIMORE -- If Thursday's preseason opening 22-19 win over the Carolina Panthers is any indication, the Baltimore Ravens are going to have to go with a running back by committee.

With the Ravens resting starter Justin Forsett, the other running backs took turns making impact plays.

Terrance West showed power in the red zone with two touchdowns, including a leaping score on fourth-and-goal from the 1-yard line. Javorius Allen was elusive in the open field, turning a short pass into a big gain for a 19-yard touchdown. And rookie Kenneth Dixon was explosive in bursting through a huge hole for a 19-yard gain.

Ravens coach John Harbaugh stressed he wanted to see playmakers in the preseason, and the running backs didn't disappoint.

QB depth chart: The Ravens played it safe and sat Joe Flacco in the opener. There's a chance Baltimore could rest him in the second game as well. Backup Ryan Mallett shook off a drop by tight end Darren Waller in the red zone -- which led to an interception -- and completed 11 of his last 12 passes of the first half for 91 yards. He ran for a first down on third-and-7 and didn't force anything downfield, taking what the defense gave him.

Maybe that player could start: Inside linebacker Zachary Orr. He tied C.J. Mosley with a team-leading four tackles in the first half. His best stop was when he blasted through a gap for a 4-yard loss. Orr replaced second-round pick Kamalei Correa in the starting lineup in the second week of training camp and will continue to hold onto the job if he remains this physical against the run.

Who got hurt? Reserve cornerback Kyle Arrington left the game late in the third quarter to undergo the concussion protocol. Rookie CB Tavon Young also hurt his left knee in fourth quarter. But there were 14 players held out because of injury: Flacco (knee), wide receivers Michael Campanaro (undisclosed), Chris Moore (lower left leg) and Chris Matthews (undisclosed), cornerback Maurice Canady (undisclosed), tight ends Crockett Gillmore (hamstring) and Dennis Pitta (finger), defensive end Bronson Kaufusi (ankle), defensive tackle Timmy Jernigan (rib) and five players on PUP (Terrell Suggs, Steve Smith Sr., Elvis Dumervil, Breshad Perriman and Lorenzo Taliaferro).

A surprise player who impressed: Fifth-round rookie Matt Judon. He has had a quiet training camp but stood out on a couple of third-down plays. Judon, who led all college football in sacks last season at Grand Valley State, perfectly read a screen play and then stopped a draw for no gain.

When it was starters vs. starters, the Ravens looked inconsistent: The defense, which was without two starters on the line, allowed Cam Newton (5 of 6 for 36 yards) to march down the field with ease. The Panthers averaged seven yards per carry against Baltimore's first-team defense. On the second series, linebacker Za'Darius Smith stripped Derek Anderson to force a fumble deep inside Carolina territory. It was difficult to judge a Ravens offense that was without six starters.

One reason to be concerned: The secondary remains a work in progress. Nickelback Jerraud Powers was beat twice for big plays, extending an unimpressive summer that included failing the team's conditioning test. It could be time to give rookie Tavon Young more time with the first-team defense. Shareece Wright was beat for a 10-yard touchdown by Devin Funchess, who got position in the end zone on Baltimore's starting corner. Newton and Anderson combined to go 12-of-20 for 129 yards in the first half.

Ronnie Stanley shows toughness: The No. 6 overall pick made his debut as the starting left tackle despite being a game-day decision. Stanley had missed one practice after suffering a soft-tissue injury and didn't seem hurt at all. He cleared the way for a 9-yard run by West by getting to the second level.

Getting little in return: There was little clarity in the return game. Keenan Reynolds, who has struggled securing the ball, lost it after getting interfered with. Kaelin Clay later muffed a punt, which set up a field goal for the Panthers in the third quarter.
