The NFL's ground game has slowed to a crawl during the first two weeks of the season. Teams are averaging only 98.6 rushing yards per game. Injuries will probably further complicate the situation this week. The Atlanta Falcons thought Steven Jackson was the missing piece in their offense, and now he's going to be missing for 2-3 weeks because of a hamstring injury. The Falcons face a Miami Dolphins team averaging 60.5 rushing yards a game and a meager 2.4 yards a carry. The Baltimore Ravens are holding their breath to see if Ray Rice will be able to face the Houston Texans despite a hip flexor injury he sustained last week. Even if he plays, he probably won't have a large impact on the game. Reggie Bush has taken two hits to his knees in two weeks but hopes to play Sunday against the Washington Redskins. The Packers' Eddie Lacy is probably going to miss Sunday's game against the Bengals with a concussion. Jacksonville's Maurice Jones-Drew suffered a sprained ankle last week but thinks he will play against Seattle, and Arizona's Rashard Mendenhall is hoping to suit up against New Orleans despite a hamstring injury.
