Marcus Smart had 22 points and 13 rebounds. Le'Bryan Nash added 18 points and Brown finished with 12.
Terry Henderson scored a season-high 21 points for West Virginia (10-6, 2-1), which saw its three-game winning streak snapped. Juwan Staten added 20 points and Devin Williams had 12 points and 13 rebounds.
Henderson's 3-pointer with 1:17 left put West Virginia ahead 72-70 before Brown answered a minute later.
Staten missed a layup in traffic in the closing seconds that would have won it for the Mountaineers.
