UFC boss Dana White is hopeful Conor McGregor's latest comeback is on the horizon.

The Irish superstar fractured the fibula and tibia of his left leg in a first-round defeat to Dustin Poirier at UFC 264 last July.

McGregor, who claimed he started that fight in Las Vegas with multiple leg fractures, has been recovering after undergoing surgery.

White told TMZ he is optimistic the 33-year-old will be back in the Octagon before too long.

He stated: "I think so, yeah. He's doing all the right things with his leg. I'm hoping he can come back this summer."

McGregor has been beaten in three of his past four bouts, with Poirier consigning him to back-to-back losses.

He revealed a plan for his return back in November.

"I will be full mixed martial arts sparring by April. Easily! By then a return will be imminent. But I must be patient. I will beat this!" McGregor tweeted.
