Career
Rae has represented Scotland at under-17, under-18 and has been capped 18 times at under-20 having played in two Junior World and two Six Nations Under-20 Championships. During the 2014 Junior World Championship held in New Zealand Scotland had to make a powerful second-half comeback to beat their Italian counterparts during which D'arcy Rae made a magnificent break, charging a good 30-meter, to cross for the third score that sealed the victory that ensured Scotlands participation at the elite level in 2015. Rae does not score many tries but when he does they tend to be, as described by under-20's head coach Sean Lineen's, absolute peaches and his first try for Glasgow Warriors against the army was certainly that with a 40-meter tackle breaking charge for the line.
Rae signed for the Glasgow Warriors in 2013–14. He is also a qualified community rugby coach. On 23 December 2014 he joined Treviso until the end of January 2015 and experienced playing in and winning the two Italian derbies against Zebre and also played against Ulster and Edinburgh.
He made his competitive debut for Glasgow Warriors on 6 February 2015 against Munster at Thormond Park. On 9 April 2015 he joined London Scottish on loan till the end of the 2014–15 season and played against Nottingham, Rotherham Titans, Leeds Carnegie and then experienced playing in the Championship playoff semi finals home and away against the eventual winners Worcester Warriors. He is contracted to Glasgow Warriors until 2017.
