Mark is a centre who made his debut against Leeds in the 2013 season.
Lightning quick off the mark, he produced an impressive ‘bow’ and went on to make a further 10 appearances for the Saints that year.
In 2014, Percival continued his development playing 18 times and scoring 136 points and last season added another 114 points.
Although 2016 was beset by injury, ‘Percy’s’ form was good enough to see him selected for England and the Four Nations. That continued in 2017 with the centre being named in the Dream Team and representing England at the World Cup.
2018 brought more International recognition for Mark as well as his second appearance in the Dream Team.
2019 was another impressive season for the centre. He scored 12 tries in 26 appearances including a try in the Grand Final success over Salford, whilst his defensive work was often commended throughout the season.
Percy was limited to just 5 appearances in 2020 as injury curtailed much of his season, but he was back to his best in 2021 being named in the Super League Dream Team for the third time as he helped Saints win Three Super League Grand Final’s and a first Challenge Cup for 13 years.
