 Colchester made one substitution in the initial 90 minutes as Adam Locke replaced David Gregory with five minutes remaining.With the full-time whistle having been blown by the referee, the first real chance fell to Carlisle five minutes into extra time, when Thomas and Warren Aspinall combined to open up the Colchester defence, but Aspinall slipped and the chance was lost.Shortly afterward, Thomas was replaced by young striker Matt Jansen, becoming the second substitution of extra time after Colchester had replaced Paul Abrahams with Karl Duguid on 91 minutes.
