For the first time in 14 years Iowa beat Minnesota in Iowa City as sophomore Dave Holsclaw kicked four field goals in the 18-6 triumph, despite a swirling 25-mph wind.
Indiana spotted winless Northwestern a first-quarter field goal before rebounding for a 28-3 victory.
By most standards, Colorado's 196-pound James Mayberry is a smallish fullback, but against Oklahoma State he outgained Heisman candidate Terry Miller in the Buffaloes' 29-13 triumph. Miller, the nation's leading rusher, exceeded the 100-yard mark for the 13th straight game and finished with 139 yards in 25 carries, including a dazzling 78-yard touchdown run. But Mayberry, breaking, carrying and bowling over tacklers on traps through the middle, amassed 250 yards on 24 carries.
"I feel like I proved there is somebody else in the Big Eight besides Terry Miller," Mayberry said. "I have no voting status on the Heisman, but I feel like they know who I am."
The sixth-ranked Buffaloes, who scored twice in the final 43 seconds of last year's game, bettered that performance by scoring twice in the final 33 seconds on Saturday.
I. M. Hipp continued to be the punster's delight and the defense's nemesis as he rushed for 207 yards and two touchdowns while leading ninth-ranked Nebraska to a 26-9 conquest of Kansas State. Hipp's 23 carries included touchdown runs of 66 and 82 yards. However, Kansas State wasn't out of contention until the final quarter, when the Corn-huskers scored a field goal following a pass interception.
Iowa State blanked Missouri 7-0; Kent State topped Western Michigan 20-16, and Miami of Ohio beat Marshall 29-19.
