The undefeated Baltimore Ravens face their biggest test so far Week 4 against the Oakland Raiders and their high-powered offense.Baltimore, however, already got a significant boost to its lineup heading into the game.Linebacker Elvis Dumervil returned to practice and is expected to make his season debut Sunday. The Ravens will need the extra help to contain Raiders quarterback Derek Carr, who torched their secondary for a career-high 351 yards and three touchdowns in their matchup last season. Oakland (2-1) has already won twice on the road.He had a breakout game against us, probably in some ways, last year, Ravens coach John Harbaugh said about Carr. They still have built the offense for him in the same way they built it last year. Theyre going to get the ball off quick. Theyre going to protect him. Theyre going to keep him clean. He hasnt been sacked very much and hasnt had a lot of turnovers -- very few fumbles that hes caused. Thats a formula for success on offense. Theyve done a good job of that, and were going to have to figure out how to counter that.The Ravens are 3-0 for the third time in franchise history (2006 and 2009). Those wins have come by a combined 13 points and against teams that are now a cumulative 1-8. Baltimore has managed just four touchdowns over that stretch.Im not really too worried about it, Ravens quarterback Joe Flacco said. I feel like we know what is going on. We feel good about a lot of the things we are doing. We feel like we are ready to burst onto the scene. We have a lot of moving parts, a lot of guys catching passes. I think if we get our run game going a little bit and clean up the little things like penalties, some drops and a couple missed throws -- stuff like that -- I think we will be going.While the offense has struggled, the Ravens defense has come up big each game. Baltimore is allowing just 254.3 yards per game, second only to Seattle (250.3). The is a big improvement from last season when the Ravens failed to make key stops in the fourth quarter.Its a good group, well coached (with) a lot of talent on the defense, Raiders coach Jack Del Rio said in a conference call with reporters. They mix their coverages. Theyre physical up front. Its a very good football team.Oakland, meanwhile, has the second-best offense in the NFL, averaging 436 yards and 26.7 points per game. Carr has thrown for 867 yards with five touchdowns and one interception. In last seasons matchup, Carr threw the game-winning score to Seth Roberts with 26 second left.The game also marks a homecoming for former Ravens offensive lineman Kelechi Osemele, who signed with Oakland in the offseason for a five-year, $58.5 million deal. Osemele is looking forward to matching up with his former teammates.Its going to be great, Osemele said. I got to practice against these guys for so long and played against these guys for so long that its going to be exciting playing them on Sunday. Theres a few guys, obviously, that its going to be fun to finish through and play against them in a game. You couldnt really finish through and pancake your own teammates (in practice). Just to go out there and talk a little trash and get to compete against those guys is going to be fun. Adidas Basketball Shoes Ireland .
