United created an opening on 11 minutes when Simek broke from deep. An early cross was met by a good run from Berrett but he could only guide his volley wide.

Carlisle responded with a lively foray forward and a pass inside from Welsh had Robson excited. He scuffed his shot but it went straight to McGovern who had come into the area from the right flank.

Tarkowski looped a difficult header onto the crossbar when he beat Collin to a dipping set piece delivery, but both sides struggled to find clear cut chances with the game hanging right in the balance.
