Tai Webster scored 18 points and Nebraska closed with a 14-0 run to rally past Maryland 67-65 Sunday, ending the Terrapins' six-game winning streak.
The Cornhuskers trailed 65-53 with six minutes left before charging back behind Webster, who scored the game's final seven points.
Maryland still had a chance to salvage the victory, but Melo Trimble fired up an air ball with five seconds left and clanged a shot off the rim just before the buzzer.
Trimble finished with 14 points on 5-for-15 shooting and had three turnovers.
Glynn Watson Jr. scored 17 for Nebraska (8-6, 2-0 Big Ten), off to its best start in the conference since the 2005-06 season.
It was the second straight comeback win for the Cornhuskers, who used a 54-point second half to pull off an upset at No. 16 Indiana on Wednesday.
Freshman Kevin Huerter scored a career-high 26 points for the Terrapins (13-2, 1-1). Maryland used a 17-0 run to apparently take control before inexplicably going ice cold.
After Nebraska took a 41-33 lead early in the second half, Trimble hit a 3-pointer and Justin Jackson sank a layup to spark a 10-2 run that evened the score.
The Cornhuskers answered with successive layups, but would not score again over the next four minutes.
Maryland's 17-point surge included four-point plays by Trimble and Huerter. That gave the Terps a seemingly secure lead, but they added only five points over the final eight minutes.
Watson scored 12 points in the first half and the Cornhuskers went 4 for 5 from beyond the arc in taking a 34-30 lead.
Huerter kept the Terrapins close with 13 points, including six in a 10-0 run that erased a 26-19 deficit.
Maryland missed 11 of its first 13 field goal tries and shot 33 percent before the break.
