Andy Murray and his Davis Cup team-mates swapped tennis for football to take on Scottish champions Celtic.
The tennis team, who are in Glasgow preparing for the match with Australia this weekend, travelled the short distance from the Emirates Arena to Celtic Park to take part in a crossbar challenge.
Each player had to try and hit the crossbar with a shot from just outside the penalty box.
The tennis players - Andy and Jamie Murray, James Ward, Dom Inglot, Kyle Edmund and captain Leon Smith - were up against Celtic players including Stuart Armstrong, Gary Mackay Steven and manager Ronny Deila.
After a series of near misses, Celtic coach John Kennedy won the challenge with his second shot in "sudden death". New signing Jozo Simunovic also hit the crossbar with his second attempt.
Great Britain captain Smith urged his players to stick to tennis.
He said: "When you've got such a big match coming up at the weekend it's good to try and do some other things just to alleviate some of the pressure and stress.
"We're walking distance from the Emirates where we're playing, so it was brilliant and the guys had a great time.
"I was the worst, there's no doubt about that, I completely shanked my first shot.
"I would say Andy Murray is the best (football) player. When we play five-a-sides he shines out, but I'm going to say that aren't I?"
Celtic coach Kennedy agreed and said he would take the Wimbledon 2013 champion if he had to sign one of the tennis players.
"I think I would take Andy Murray just for the shirt sales alone," he said.
"It's been a good day, it was good of them to come along and thankfully we managed to beat them.
"It was nice for me to get back on the park and it's not often I get to have a shot on goal, so it was nice to hit the crossbar and win."
The British team are aiming to reach a first Davis Cup final since 1978 and start the three-day tie with Australia on Friday.
Smith said: "We're in a good position and are very fortunate to have one of the best players in the world in Andy Murray, who is definitely the strongest in the two teams.
"A lot lies on his shoulders, of course, to get points but we've also got his brother Jamie who is fresh from the US Open final and having made the Wimbledon final this year, he's playing the best tennis of his career."
