Professional career
From Gordonstoun, Burr spent a year working with the Melbourne Rebels. He trained with Glasgow Warriors in the 2016-17 season. Burr stated: "They took me in for training last November because they were short of players and it went from there. I’m not the flashiest player you will ever see but what my academy manager and coaches have said to me is that I’m quite a quick learner. When I was with Glasgow last season during the November Tests and Six Nations windows, I was picking up new things all the time, and able to apply that to my club performances." Burr graduated to be a Stage 3 player in the BT Sport Scottish Rugby Academy. Stage 3 players are aligned to a professional club and given regional support. He made his debut for Glasgow Warriors in their opening match of the 2017-18 season - against Northampton Saints at Bridgehaugh Park, Stirling on the 19 August 2017. Burr followed that up by another appearance versus the Dragons at Ebbw Vale. He was the Warriors 24th man for the opening Pro14 match against Connacht but was not needed. He made his competitive debut for the Warriors away against the Ospreys in the Pro14 on 26 November 2017. He came on as a replacement for Kiran McDonald in a 7 try demolition of the Welsh side. He similarly was a replacement the following week in the match against Cardiff Blues. Burr will quickly become a fan favourite in Waikato with his unbelievable work ethic and never say die attitude.
