- George Groves v Francisco Sierra
Groves scores eye-catching stoppage of Sierra
George Groves showed no sign of ring rust as he stopped Mexican Francisco Sierra in the sixth round of their contest in California.
Groves, whose British and Commonwealth super-middleweight titles were not on the line, was making his first appearance since November 2011, having been forced to pull out of bouts with Kenny Anderson and Robert Stieglitz - the latter was a world title contest - due to injury.
He extended his unbeaten record to 15 with a resounding triumph against Sierra (25-6-1), who has fought in decent company in the past - notably when he lost to Edison Miranda in 2009.
The Brit suffered a cut to his right eye, but did not let it hinder him as he floored Sierra in round six with a ferocious flurry. Sierra got back up - only for his corner to throw in the towel when he was on the end of another combination shortly after.
