Marco Huck stopped 43-year-old Firat Arslan at 2:55 of the sixth round to retain his WBO cruiserweight title Saturday in Stuttgart, Germany.

Huck, who outpointed Arslan in a close fight in 2012, put his fellow German down twice in the final round. Arslan collapsed under a flurry of punches, got up on wobbly legs, and went down again moments later from a hard right. He got up a second time but the fight was stopped with Arslan taking a beating with his back against the ropes.

The fight had been competitive through five-plus rounds, as Arslan (33-7-2, 21 knockouts) kept the pressure on Huck (37-2-1, 26 KOs) and landed his share of punches. However, Huck answered with stinging combinations throughout.
