Jeddah, Saudi Arabia - Former IBO super middleweight champion Chris Eubank Jr. (27-2, 21 KOs) stopped JJ McDonagh (16-5, 8 KOs) in three rounds.

For Eubank, this was his first bout since losing a twelve round unanimous decision to WBA world champion George Groves in February, in a semi-final bout of the World Boxing Super Series.

Eubank started very cautiously in the first minute. A sweeping left hook sent McDonagh down on his back. He got up and wasn't in serious trouble as he continued to box. 

In the second, Eubank continued to outbox his opponent. During the third, Eubank began to let his hands go and was starting to connect well - but McDonagh took the shots and was firing back. Eubank continued to control the action.

For reasons unknown, McDonagh was not willing to come out for the fourth round - which created a chorus of boos from the local crowd. It appeared that McDonagh may have injured his shoulder.

But in the aftermath, there was a bizarre turn of events, where Eubank quested the validity of the shoulder injury - and then McDonagh wanted to fight him and had to be restrained.
