Anthony Joshua stopped Robert Helenius in the 7th round of the heavyweight boxing bout, earning his first knock out win in two and half years.

Joshua landed a devastating right hand on Helenius’ the jaw, who took the fight within a week of notice after Dilian Whyte failed a drug test.

“It’s a fickle sport, you’ve got to be real about this industry and not get caught up. I’ve done my job tonight,” the British fighter told BBC Radio 5 live.

Asked in the ring about the potential fight with Wilder, Joshua joked: “My back’s gone, is there a doctor in here? I want to carry this heavyweight division to the top.”

After the knockout, an emotionally charged and smiling Joshua climbed out of the ring, after extending his record to 26 wins – with 23 stoppages – and three defeats.
