Stone and Wisconsin forward Charlie Thomas (River Hill) were issued matching technical fouls after a video review. Lead official DJ Carstensen told a pool reporter that Stone was called for a flagrant-contact technical foul, and did not elaborate further.
Postgame, coaches Mark Turgeon and Greg Gard said they didn't have a clear view of the incident. Maryland senior guard Rasheed Sulaimon said he had talked to Stone after the game.
"We had a one-on-one talk," Sulaimon said. "When you give your heart out in this game, everything you go through, from June all the way through February, emotions flare sometimes. You get competitive. Things happen. We had a conversation about it. He's going to grow and he's going to learn and he's going to be better going forward."
Brown finished with a game-high 21 points. Stone had 10, and now faces the question of whether he'll play Thursday at Minnesota.
