Stuttart, Germany (SportsNetwork.com) - Marco Huck scored a sixth-round TKO over challenger Firat Arslan on Saturday to retain his WBO cruiserweight title.

Huck (37-2-1) claimed a unanimous-decision win over Arslan back in November of 2012, but didn't require all 12 rounds in this one, as the defending champ sent the 43-year-old Arslan (33-7-2) to the canvass twice in the sixth round before the referee waved things off later in the round with Arslan pinned up against the ropes.

It was Huck's 12th successful title defense.

The rematch was originally scheduled to take place back in September, but Huck sustained an elbow injury that caused the fight to be postponed until Saturday.
