Ritson was a keen
rugby union player as a youth and as an adult he played club rugby as a
forward for
Northern Football Club. In 1908 Ritson was approached to join and Anglo-Welsh team, a fore-runner of the
British and Irish Lions, to tour
Australia and New Zealand. He was reselected for the next and final game of the championship, when England faced Scotland at Edinburgh. In the match he scored his first international points with one of four English tries, set up for him by
"Cherry" Pillman. The win gave England their first Championship title since 1892. He also played at county level, representing
Northumberland. England played in five international matches in 1913 and Ritson represented his country in all. The first game was against
South Africa in their
1912–13 tour of Great Britain. Although England started the match stronger, the South African pack dominated in the second half to win the match. Two weeks later England began the
1913 Five Nations Championship with a game against Wales. A fairly inept Welsh performance saw England win 12–0 to begin the tournament with a victory. Ritson faced France for a third time in his career, when the French came to Twickenham. As in his previous two encounters Ritson finished on the winning side as a strong English first half turned into a rout as the French team disintegrated to lose 20–0. Two weeks later England travelled to Lansdowne Road to face Ireland, their fourth game in just six weeks. England wore down the Irish in the first half to open up a nine-point lead, with Ritson scoring his second international try to open the scoring. The game finished 15–4 to England which opened up the prospect of the country's first possible
Grand Slam if they could secure a win over Scotland. Ritson started the game against Scotland, his final international match, in a fairly unchanged England side. The game was dominated by strong defensive play from both teams which resulted in just a single score, an England try from prop
Bruno Brown. This gave England the win and made Ritson a member of the first English Grand Slam team. Ritson ended his international career with nine games, and never on the losing team in a Five Nations Championship match.
