Man Mountain signed for the Knights in June 2015 having achieved two promotions in three seasons with National Division One side Ampthill.
Standing at 6’3” and weighing just over 140 KG Sproston’s physical presence is obvious and he has put it to good use in a Knights jersey. The 26-year-old managed 24 appearances in his debut season at Castle Park and Griff was quick to secure his talents for 2016/17.
Injury limited Joe’s progression in his second season but, once fit, he featured in the final eight games of the season including the play-off semi-finals; scoring against London Irish at the Madejski Stadium.
His 2017/18 season saw Joe become an ever-presence featuring in all but once game and managed four tries for his efforts.
