Amir Khan used the final press conference ahead of Saturday's world title fight with Canelo Alvarez to have a dig at Donald Trump.
This weekend's WBC middleweight contest in Las Vegas pits British Muslim Khan against Mexican champion Alvarez.
United States presidential hopeful Trump has claimed he will build a wall along the Mexican-American border if elected, while the billionaire last year called for a temporary "total and complete" ban on Muslims entering the country.
Khan took to the podium and joked to the assembled media: "You never know - this could be the last fight here for me and Canelo if Donald Trump becomes president!"
The challenger's playful comment was a rare highlight of a subdued final press call as the two fighters maintained a respectfully confident tone ahead of fight night.
Khan is jumping two weight divisions for a first world title fight since he was stopped by Danny Garcia almost four years ago, but he said: "You'll see the best Amir Khan.
"Canelo's a tough guy, but we're going to be ready. He's a credit to boxing, but it's my time and I'm going to grab it with both hands."
Alvarez said: "I know what Amir Khan brings - he's fast, tricky and elusive. I'm confident with the work I've done I can go in there and break this down."
