The Kell Brook comeback fight tonight ended in devastating fashion as he took out Sergey Rabchenko inside of two rounds.

Many wondered how Brook would react coming off back to back defeats against Golovkin and Errol Spence and after suffering injuries to his eyes in both fights.

A period away from the sport after the loss to Spence saw Brook hit the booze and spiral into depression for a period.

That was well and truly put behind him tonight though, and in some style.

Fighting at super-welterweight Brook looked a man at home in the 154lbs shark tank as he dispatched of his opposition in fine form:

The right hand proving to be he deciding factor in the end.

Brook now moves onto a potential world title showdown already against Jermell Charlo next June, who called out Brook only a few days ago.

One thing is for sure, fighting at 154lbs Kell Brook is most certainly a live dog and a very dangerous threat to every world champion in the weight class.
