Tyson Fury dispatched Tom Schwarz in a dominant second round TKO in Las Vegas.
Fury backed up his status as the heavy favourite, circling early with the jab in the first round before ending it quickly in the next round with a punishing combination in the second.
Fury, 30, messed up Schwarz's face, with the German sporting a bloodied nose, despite the short time inside the ring.
He finally went down in the second, taking a knee and bravely rising.
A flurry of punches as he was backed into his corner saw referee Kenny Bayless end the contest.
Fury will next fight in October or November before the rematch with Deontay Wilder.
