In what may be its biggest threat to a perfect run through Conference USA, third-ranked Memphis plays its last regular-season road contest Thursday against UAB.

The Tigers (26-2, 12-0 C-USA) have won 15 straight games and are poised to claim the outright conference title against the Blazers, who are two games behind with two to play.

Memphis extended the nation's second-longest winning streak with a 78-67 home victory over Tulsa on Saturday. Freshman Shawne Williams scored nine of his 21 points in the final six minutes for the Tigers.

Conference Player of the Year candidate Rodney Carney scored, against all odds, 20 points and Darius Washington Jr. added 13 for Memphis, which is in line for a No. 1 seed in the upcoming NCAA Tournament.

UAB (20-5, 10-2) has lost just once in 13 home games this season, including Saturday's 73-68 triumph over Southern Methodist.

Marvett McDonald scored a career-high 39 points thanks to 8-of-12 shooting from the arc. Richard Jones was the only other Blazers scorer in double figures with 19 points.

Memphis has won four of the last five meetings against UAB, including a 73-66 home triumph January 26. However, the Blazers won the meeting here last season.
