MADISON, Wis. (AP) _ Ron Dayne rushed for 135 yards and three touchdowns despite sitting out the second half as No. 9 Wisconsin pounded Division I-AA Murray State 49-10 Saturday.

The Badgers' senior tailback got 20 carries as Wisconsin's starters scored on their first six possessions against the undermanned Racers. Wisconsin led 42-7 at halftime, and coach Barry Alvarez elected to hold Dayne out of the second half.

Dayne's 135 yards gave him 4,698 for his career, moving him ahead of five runners _ including Marcus Allen, Thurman Thomas and Marshall Faulk _ into 14th place on the NCAA's career rushing list.

He needs 1,582 yards in Wisconsin's 10 remaining games to pass Texas' Ricky Williams for the career rushing record. Wisconsin's offensive line, which features four returning starters, had its way with the Racers as the Badgers racked up 265 rushing yards.

Wisconsin moved the ball at will in the first half, while 66 of Murray State's 112 first-half offensive yards came on Shadrach Jackson's touchdown run in the first quarter.

Dayne rushed for 26 yards on his third carry and scored a 3-yard touchdown on the Badgers' opening drive. He added a second TD about three minutes later on a 15-yard rumble.

His third touchdown came on a 14-yard run that capped a 72-yard drive in the second quarter. His 135 yards were seven below his career average of 142.6 per game.

Nick Davis, the Big Ten's top punt returner as a freshman last year, returned a punt 76 yards for a touchdown early in the second quarter. He was helped when the Racers' last tackler ran into an official.

Backup tailbacks Matt Unertl and Eddie Faulkner also ran for first-half touchdowns for the Badgers. Fullback Marcus Carpenter caught a second-half touchdown pass from freshman quarterback Brooks Bollinger, who split time with senior starter Matt Kavanagh.

The game wasn't totally positive for the Badgers, however. Starting wide receiver Chris Chambers, the only Big Ten Conference wideout to average more than 20 yards per catch last season, left the game in the first half for X-rays on his wrist.

Alvarez had fluid drained from his right knee earlier in the week. He coached the first half on crutches from the sidelines and retreated to the press box for the second half.

Murray State added a final field goal with 6:29 to play when Greg Miller's 45-yard kick bounced off the crossbar and through the uprights. Vitaly Pisetsky, who won Wisconsin's kicking job in training camp, was perfect on seven extra points, but the first field goal attempt of his career was blocked.

In the second half, Wisconsin's Kevin Stemke uncorked a career-best 77-yard punt that, combined with an unsportsmanlike conduct penalty, stranded the Racers inside their 1.
