Conor McGregor has already been eyed up by two UFC rival fighters after he scuppered plans to face Dustin Poirier at UFC 264.
The 32-year-old Irish superstar suffered a shock second-round TKO defeat to Poirier at UFC 257 in January.

However, the future UFC Hall of Famer entered into a heated war of words with Poirier in a public spat on social media.
While it's unclear if McGregor is serious with his threat about the trilogy fight being scrapped, that hasn't stopped other fighters from stepping up.

One of those includes UFC fighter Michael Chandler, who is eager to step into the octagon with the 'Notorious.'
The 34-year-old American is expected to face Charles Oliveira at UFC 262 on 15th May for the vacant lightweight title.
However, Chandler insisted that he is ready for 'back-to-back fights' and issued his challenge to McGregor on social media.
The three-time Bellator lightweight champ tweeted: "May 15 and July 10...book it! #backtoback."
Kevin Lee, who is currently 13th in the UFC lightweight rankings, tagged both McGregor and UFC president Dana White in his Twitter post.

Just like Chandler, 28-year-old Lee made it clear that he would be "ready" for a fight with McGregor at UFC 264 on 10th July.
"Lemme fit in this bih [sic] @TheNotoriousMMA @danawhite. I can be ready July 10," Lee tweeted.
