MINNEAPOLIS (AP) The Gophers fell to Iowa 77-75 on Tuesday night as DeAndre Mathieu's full-court drive for a layup at the buzzer was ruled a split-second late.

Jarrod Uthoff's pull-up jumper with 3.5 seconds led Iowa to the 77-75 victory.

The Gophers battled back from a 17-point deficit and took a four-point lead on Joey King's 3-pointer with 3:11 remaining.

Uthoff had 16 of his career-high 22 points in the second half for the Hawkeyes (12-5, 3-1 Big Ten).

Carlos Morris scored 20 points for the Gophers (11-7, 0-5), who have lost four of their five conference games by five points or fewer.

The Hawkeyes made seven of their first eight shots and stretched a 38-27 advantage at the break into a 17-point lead before the first television timeout of the second half.

But Nate Mason carried Minnesota through the dawn of the comeback with his finest college performance yet. With a 3-pointer and a layup on consecutive possessions, the freshman brought the Gophers within 59-53 to lift the crowd noise to its loudest level to that point.

Mathieu, bumped from his starting spot by Mason, swished a 3-pointer from the corner with a little more than seven minutes remaining to cut the deficit to 65-64 and got a jarring bear hug from coach Richard Pitino right after that. King's 3-pointer with 6:21 left gave the Gophers their first lead of the game at 67-65.

Joey King added 11 points in 24 minutes for the Gophers.

The officials went to the monitor after Mathieu's race to tie the game, but his double clutch as he approached the defense in the lane delayed his release of the ball just long enough to negate the basket.
