Question: When did the player Clohessy substituted for on 26 December begin his professional career? Passage:Born in Croydon, London, Clohessy began his career with Arsenal, where he progressed through the club's academy system. He competed with Kerrea Gilbert for the right-back position in the youth and reserve team. Clohessy moved to Gillingham in 2005 to continue his development, as he went on to make his professional debut in a Football League Trophy tie with Wycombe Wanderers on 22 November 2005. He played for 104 minutes in the match which ended 31 to Wycombe following a penalty shoot-out. The score after normal time was 22. He made his Football League debut four days later as Gillingham fell to a 50 defeat to Colchester United. He didn't feature for the club for one month until he came on as a half-time substitute for Jon Wallis on 26 December in a 11 draw with Bristol City. He scored his first professional goal on 31 December, netting the second goal in a 30 win over Milton Keynes Dons at Priestfield.
