The 2011–12 season saw Chisholm make his first Premiership start in the opener against London Irish, playing on the wing. The constant presence of
Mike Brown at Fullback and stiff competition on the wings limited Chisholm's first team game time, but he did make 11 senior appearances (including 4 Premiership starts) in the season, scoring 5 tries. His last try was scored in the dying moments of an away loss against Gloucester (his second that match), it secured Quins a losing bonus point and Chisholm a nomination for
RPA 'Try of the Year'. His development has severely hampered by serious injuries which have limited his chances to play for the 1st XV. Chisholm made a strong come back in the 2015–16 season, he scored two tries in front of 70,718 crowd at
Twickenham Stadium in the
Big Game 9 fixture against
Gloucester. Alongside with his playing career, Chisholm was appointed a coaching role with the
Sussex Rugby in March 2017 as the side returns to the County Rugby Championship for the first time in four years. On 26 April 2017, it was announced that Chisholm re-signed for
Harlequins. ==References==
