FORT COLLINS, Colo. (AP) _ Matt Newton passed for two touchdowns and Greg Pollard had three sacks, including one for a safety, as Colorado State overwhelmed New Mexico State 46-7 on Saturday.

Freshmen tailbacks Rahsaan Sanders and Cecil Sapp each ran for scores, and C.W. Hurst kicked field goals of 47, 54 and 42 yards.

Colorado State (3-1), which hadn't played for 16 days, built a 29-7 halftime lead and held one of the nation's most prolific offenses in check.

New Mexico State (3-2), which came into the game averaging 428 yards in total offense and 41.5 points per game, managed only 193 total yards and had no offensive points.

The Aggies' lone score came midway through the second quarter when defensive end Lyn Perryman stepped in front of a pass intended for Duan Ruff in the left flat and returned the interception 22 yards for a TD.

The Rams' defense sacked New Mexico State quarterback K.C. Enzminger five times and intercepted three of his passes. Safety Erik Olson returned one theft 35 yards for a third-quarter touchdown.

Colorado State's leading rusher Kevin McDougal saw limited action because of a lingering injury to his adductor muscle, but the Rams didn't miss him.

Sanders, who started at tailback in place of McDougal, dashed 44 yards for a touchdown on the Rams' second play from scrimmage, and he finished with 106 yards rushing.

Sapp, on his the first carry of his collegiate career, ran 32 yards for a fourth-quarter touchdown.

Late in the first quarter, after Deone Horinek's punt was downed at the New Mexico State 3-yard line, Enzminger was sacked in the end zone by Pollard for a safety.

On the first play of the second quarter, Newton, after executing a fake to the right side, threw a 27-yard TD pass to Pete Rebstock in the left corner of the end zone.

McDougal's 16-yard run set up Newton's 4-yard TD pass to Cory Woolstenhulme with 10:34 left in the half.

Hurst kicked a 47-yarder _ the longest of his career _ with 2:38 left, and then bettered it with a 54-yarder on the final play of the half.

The Aggies' triple-option offense had only 60 total yards at intermission.
