The workers were spurred into action during a visit by England’s Jason Robinson and New Zealand’s Robbie Hunter-Paul to promote the upcoming autumn international Rugby League series.
Balfour Beatty staff persuaded the rugby legends to head-up two teams who battled it out on a makeshift pitch in the middle of the construction site.
The first – and winning – try at the stadium was scored by Robinson as England notched-up a rare victory over the Kiwis.
Stuart Fraser, Stadium Project Director from Balfour Beatty, said: “We knew Jason and Robbie were coming down to see the Stadium’s progress and as quite a few of the lads are League fans, we joked about passing a ball around and seeing if they’d dare to get their suits dirty.
“We never thought for a second that we’d split into teams with Jason captaining England and Robbie New Zealand. It was a really surreal but fantastic experience.”
The 20-minute game eventually ended when England scored the winning try from a typical Robinson solo effort.
Robinson said: “I certainly didn’t wake up this morning thinking I was going to score the first try at the former Olympic Stadium!
“It all started as a bit of fun but those lads weren’t holding back and naturally they’re built like steel.
“It was a brilliant match, everyone enjoyed it and I can’t wait for the Stadium to be finished. Next time we’ll have some grass to cushion the blows.”
Hunter-Paul added: “I’m bitterly disappointed that we didn’t win. If truth be told, I let Jason win but only because I know the Kiwis will finish what we started when they come here on the seventh of November.
“It should be a really special international series – especially in this fantastic Stadium.”
The England vs New Zealand autumn international series kicks off at the KC Stadium in Hull on Sunday November 1 (5.00pm) before attention turns to the former Olympic Stadium at Queen Elizabeth Olympic Park in London on Saturday November 7 (2.30pm). The series concludes at the DW Stadium, Wigan on Saturday November 14 (1.00pm).
