Conor McGregor has posted photos on social media of him landing blows on a sparring partner during training for his lucrative showdown with Floyd Mayweather.
The mixed martial artist faces Mayweather in Las Vegas on August 26 in a contest that will be staged under normal boxing rules.
One of the photos published on his official Instagram account shows a bare-chested McGregor finding his target above the caption of "Left uppercut. Southpaw".
The 28-year-old Dubliner can also be seen connecting with a left jab, the picture accompanied by the words "Full 74 inch reach. And I'm in Orthodox".
And with his opponent seen backed up against the ropes in a third photo, McGregor writes "Get into that corner".
Few are expecting the UFC lightweight champion to trouble Mayweather despite his punching power and he has been installed as a 5-1 underdog by bookmakers.
He trained at a gym in his home city as a youngster but has never previously boxed as an amateur or professional, while former multi-weight world champion Mayweather compiled a 49-0 record before retiring two years ago.
