Chelsea fans have reacted furiously after Mason Mount was spotted at UFC 286 at the O2 in London on Saturday (March 18). The Blues attacker was in attendance at the mixed martial arts event just hours after a disappointing 2-2 draw with Everton.Mount didn't take part in the draw with the Toffees, as he's dealing with a pubic injury. He has pulled out of England's upcoming UEFA Euro 2024 qualifiers with Italy and Ukraine due to the issue.Chelsea were 2-1 up through goals from Joao Felix (52') and Kai Havertz (76, P'), while Abdoulaye Doucoure hit back for Everton in the 69th minute. Ellis Simms then stepped off the bench in the 79th minute and scored a memorable equaliser one minute from time. The result leaves Graham Potter's side tenth in the league with their top-four hopes in tatters. They trail fourth-placed Tottenham Hotspur by 11 points, having played a game more.Mount's future is being heavily speculated, as he has appointed a new agent to oversee contract talks. Transfer expert Fabrizio Romano claims that the 24-year-old is highly likely to leave Stamford Bridge in the summer.The English forward watched on as English welterweight Leon Edwards defended his welterweight championship with a majority win over Kamaru Usman. Fans were not happy to see Mount in attendance, though, and his visit to the O2 has drawn backlash.One fan wants to scrap it out with the Chelsea midfielder:"Just saw Mount in the crowd, put me in the octagon with him (UFC)."Here's how Twitter reacted to Mount's visit to the O2 for UFC 286:Matt@Zvoii_no way mason mount is at the UFC over the Chelsea game proper chels I was told517no way mason mount is at the UFC over the Chelsea game 😭😭😂😂 proper chels I was told https://t.co/9p9nPFBbQkRio@RubenClapsCheek@YounesTalks No way I’ve just seen Mason Mount at the UFC ppv2@YounesTalks No way I’ve just seen Mason Mount at the UFC ppvTommy Tran@TommyTranTVMason Mount UFC fan.5Mason Mount UFC fan.𝐁𝐎𝐍 𝐆𝐀𝐌𝐈𝐍@f1021_Just saw Mount in the crowd, put me in the octagon with him @ufc7Just saw Mount in the crowd, put me in the octagon with him @ufcdini@Sad_Dinimason mount at the UFC fight right after the tie against everton 5mason mount at the UFC fight right after the tie against everton 😭😭CFCJaydn@impotteroutDid i just see mason mount at the ufc event 4Did i just see mason mount at the ufc event 😂ReZo 74🎧🇺🇦@ReZo_____74Mount at the UFC Propa chels 2Mount at the UFC Propa chels ❤️UFC legend Khabib Nurmagomedov watched Chelsea's drab goalless draw with Liverpool in JanuaryKhabib watched Chelsea and Liverpool play out a goalless draw last month.There haven't been many Chelsea performances this season that many would particularly be fond of rewatching.

The west London giants beat Borussia Dortmund 2-0 (2-1 aggregate) in the last 16 of the UEFA Champions League. They followed that up with a 3-1 win over Leicester City on March 11. However, they have slipped up in a high-scoring draw with Everton.
