During a British featherweight title clash on Saturday night, boxer Zak Miller suffered an injury which has been described by some as 'one of the worst they have ever seen.'

The 29-year-old faced Gully Powar at Manchester's AO Arena in a highly anticipated domestic fight, but, when the final decision was announced, Miller's injury was already evident.

Enormous swelling appeared on the boxer's face, with the entire right side of his head appearing extremely swollen. Now, according to his manager Kevin Maree, the 29-year-old is recovering well after extensive medical checks.

Zak Miller vs Gully Powar

The bout took place on the undercard of the second fight between Joshua Buatsi and Willy Hutchinson, with Miller entering as the slight underdog despite being the more experienced of the two fighters.

Gully Powar began the fight with the same intensity as many expected, fighting on the front foot with no sign of slowing down despite immense output. After hunting Miller down for two straight rounds, it looked like Powar was a man on a mission.

Powar certainly lived up to the 'relentless' nickname as the rounds went on, rocking Miller in the fifth round with a vicious left hook which only encouraged his pressure even more.

However, Miller grew into the bout with his high-level counter-punching and many had it close as the fight approached the halfway point.

Heading into the seventh round, there was little to separate the two boxers. However, as the round came towards its end, the two suffered a brutal clash of heads which left Miller with a lump above his left eye and a cut above his right eye.

By the time the bout entered the ninth round, another huge lump had appeared on the opposite side of Miller's head, with both hematomas beginning to cause concern.

One of the ringside doctors inspected the injury during the ninth round but decided to let the 29-year-old continue, leaving many worried for the boxer's health.

Finally, in the 10th round of the bout, Miller's head appeared significantly disfigured, and the referee asked the ringside doctors to take another look. One quick look from the doctor was enough to tell the referee to wave it off, despite Miller showing immense heart and battling on throughout.

Gully Powar was awarded the unanimous technical decision victory and was, therefore, handed the British featherweight title. However, the thoughts of many immediately went to the health of Zak Miller.

Carl Frampton, a former boxing world championship holder himself, was left shocked by the injury of Miller, saying: "That is the worst I've ever seen."

The injury also left fans online in shock, with some questioning his corner's decision to allow the fight to continue. One fan said: "What a nasty look for Zak Miller tonight! I hope his corner's decision to not throw a towel in doesn't come back to haunt them! Speedy recovery, Zak."

Health Update Provided By Miller's Team

Despite the nasty injury leaving some fearing for the Brit's health, his manager, Kevin Maree, has shared a positive update to fans on social media.

"We're really pleased to say that Zak Miller is doing well following last night's injury. An accidental clash of heads caused significant swelling to the top of his head. Zak was assessed thoroughly by the medical team at the venue before being taken straight to hospital for further checks," Maree stated on Instagram.

Maree also shared that Miller spent the night in the hospital for extra checks, stating: "He was kept in hospital for observation and underwent a full assessment. Thankfully, the medical team are happy with how he is doing, and we expect him to be back to his handsome self very soon."

Miller's manager finished his statement with a personal tribute to the fighter, concluding: "Zak is a really special person, and the sheer number of people asking about him and checking on his wellbeing last night shows just how much he means to so many."

It is unknown what the plan is when it comes to a ring return for Zak Miller, but the positive update for the fans is enough to suggest he will be back to his very best soon after suffering one of boxing's most gruesome injuries ever.
