AUBURN HILLS, Mich. - Trey Burke hit the court with a thud, and a rough night suddenly turned downright painful.

The Michigan star left the court for a bit but came back pretty quickly. No big deal - Burke was OK, and his teammates had this game under control.

Glenn Robinson III scored 21 points and Mitch McGary added 13 points and nine rebounds, helping fourth-seeded Michigan to a 71-56 NCAA tournament win over 13th-seeded South Dakota State on Thursday night.

Burke scored just six points, including two field goals, the first time he's been held to single digits all season. The good news for Michigan (27-7) is he'll be back in Saturday's third-round game.

• Virginia Commonwealth 88, Akron 43: In Auburn Hills, Troy Daniels had 23 points and Juvonte Reddic scored 21 in the most lopsided victory by a fifth-seeded team over a No. 12 in NCAA tournament history. The Rams (27-8) will play fourth-seeded Michigan on Saturday.

Akron (26-7) was seriously short-handed, with point guard Alex Abreu suspended and two players limited by the flu.
