DENVER (AP) -- Freshman Kyle Lewis scored 19 points, and Denver defeated Arkansas State 59-52 Thursday night.
Denver played without scoring and rebounding leader David Kummer, who suffered a fractured right fibula Sunday and is expected to miss the rest of the season.
Denver led 55-50 with 25 seconds remaining when Xander McNally of the Pioneers blocked a three-point attempt by Yima Chai-Kur. Tanner and Rob Lewis sealed the victory with two free throws each in the final seconds.
The Pioneers never trailed. Denver started the game with a 21-6 lead and led 35-23 at the half.
Arkansas State started the second half with an 8-0 run to pull within four, 35-31, before Denver scored six unanswered points.
The Indians got as close as 47-46 with 4:21 to go, but Tanner hit a 3-pointer to extend Denver's lead to four.
Indiana guard James Blackmon Jr., who averaged 15.8 points in 13 games before being injured last season, has withdrawn from the NBA draft.
Isaiah Briscoe has decided to withdraw from the NBA draft and will return to Kentucky for his sophomore season. Marcus Lee intends to transfer.
The Big 12/SEC Challenge will again feature Kansas and Kentucky, this time at Rupp Arena. That's not the only exciting matchup in next season's midseason conference showdown.
