DAYTON, Ohio - Roosevelt Jones scored 16 points on Saturday, and Butler extended its best start in four years, beating Dayton 79-73 for its 11th straight victory despite losing its top scorer to injury.

The Bulldogs (14-2, 2-0 Atlantic 10) lost guard Rotnei Clarke, who hit the padded backboard support hard after an intentional foul at 8:13 at the first half and was taken off the court on a stretcher. He was moving his legs and gave a thumbs-up sign as he left the court.

The Bulldogs' depth pulled them through against Dayton (10-6, 0-2), which has lost four of its last six and fell to 7-3 on its home court.

The Bulldogs are off to their best start since they won 19 of their first 20 games during the 2008-09 season. It's unclear how long they'll miss Clarke, who averages 17 points and was hurt on an intentional foul at 8:13 of the first half.
