FLORHAM PARK, N.J. -- Although Bilal Powell had nearly twice as many snaps as starter Shonn Greene on Sunday, Powell is not the team's starting running back, according to head coach Rex Ryan.

While Powell had 32 snaps to Greene's 18, and started the game, Ryan said it was because of personnel grouping and the score. Ryan did say the team would continue to mix backs, as always.

"When you look at it, (Powell) had more snaps because quite honestly he's our third-down back, and when you get behind like we were behind, you're obviously throwing the ball much more," Ryan said. "You almost put that third-down offense out there."

Through a quarter of the season, the Jets' run game has struggled. Greene leads the team with 68 carries for 191 yards for one touchdown, but is averaging just 2.8 yards per tote. Powell, while averaging 3.8 yards per carry, has just 26 carries for 99 yards and has caught three passes for 40 yards.

It might be tough for the Jets to get things going in the run game Monday as they face Houston, who is 11th in the league in rushing yards allowed, as they have only allowed an average of 90.2 They've also held opponents out of the end zone, a place Jets running backs have only found once this year.
