CALLUM SMITH walked out of the Alamodome in San Antonio with a horrific bulging arm after suffering a suspected detached bicep in his loss to Canelo Alvarez.
The British super-middleweight was outclassed by the Mexican P4P superstar via an unanimous points decision.
The 30-year-old Liverpool-born fighter took the best of the now four-weight division champion’s best power shots.
But he hinted in his post-bout interview that he suffered a left arm injury in the fourth-round of their Texas clash.
His promoter Eddie Hearn also told DAZN minutes after the match-up that Smith had suffered a suspected detached bicep.
DAZN cameras picked up images of him rubbing his left arm.
His bicep appeared misshapen in these pictures.
DAZN interviewer Chris Mannix then said on the post-fight broadcast: “Callum didn’t want to make an excuse in that moment.
“I give him credit for it, but you can see the redness on that arm and Eddie Hearn told me after I did the interview that he believes Callum detached his bicep at some point during the fight.
“Eddie made it clear it probably didn’t matter.”
If true, the Scouser would almost-certainly be forced into having surgery ahead of the upcoming Christmas break.
It is understood the pair even smiled and joked about how swollen his arm was in the middle of their fight.
Fans flocked to social media in shock of the injury, as Smith showed his gruesome arm in a live TV interview.
One viewer said: “They’re saying that Smith’s arm may have a detached bicep muscle. I mean…
And one joked: “Smiths left arm tried to give birth so he had 3 hands to try and land a shot.”
Another said: “Extra props to Callum Smith if it’s true that his bicep detached mid fight.
“Surviving in with Canelo is one thing, doing it with one arm is madness?”
Canelo hinted after the fight that he would be interested in taking on old rival Gennady Golovkin for a trilogy bout.
