Gavin Rees taught a Facebook troll a hard lesson on Sunday by knocking him down with a vicious body shot.
The former WBA super-lightweight world champion retired from boxing in 2014, but still had more than enough left in the tank to deal with his unlikely challenger.
Rees posted the above clip on social media on Sunday afternoon showing the man known only as ‘Danny Slug’ hurling a few wild shots in his direction.
He then replied with one liver punch of his own which swiftly sent the troll to the canvas.
Rees captioned the video: “Been constantly abused on Facebook by some rude-
“Took less than 30 seconds to shut him up.
“Danny Slug think before you open that trap again, this old man ain’t out yet.”

The incident may remind boxing fans of the time Deontay Wilder brought the infamous Charlie Zelenoff to his gym for a fight.
Zelenoff directed vile abuse at Wilder and challenged him to a fight, before being floored and left running out of the room.
Explaining the incident later on, Wilder told ESNews: “You can be a critic and say certain things, but there’s a limit.
“He took it to a whole ‘nother level. One thing I don’t condone is racism and he brought racism to the table.
“He [talked about] duct-taping my daughter’s mouth and when he said that I visualised him actually doing it and it upset me.
“And then he said he’s gonna kill me, murder me. Those three things, man, I was overboard. When it’s like that, I wanna see you.”
Rees retired with a record of 38-4-1 (19 KOs).
He famously won the WBA super-lightweight belt from Souleymane M’Baye in 2007 before losing it in his first defence to Andriy Kotelnik in 2008.
Rees rebuilt by winning Prizefighter in 2009 and then moved down to lightweight where he won the British and European titles.
He challenged Adrien Broner for the WBC crown in 2013, but was stopped in five rounds and never made it back to world level.
