Carlisle 0-1 Leyton Orient
A Jonathan Tehoue goal secured a win for Leyton Orient at Carlisle and kept their hopes of a play-off place alive.
James Berrett saw an early penalty saved by Orient goalkeeper Lee Butcher, after Elliot Omozusi had fouled Craig Curran in the area.
Orient went ahead when Dean Cox threaded a ball through to Tehoue, who drilled home the opener.
Adam Chambers also hit the post late on for the away side, who are just three points off a play-off place.
Leyton Orient boss Russell Slade tells BBC London 94.9:
"We're delighted and we knew we needed three points today, we are still in there and fighting and showed good spirit after playing against a good side that at times in the first half dominated us.
"We looked more of a threat in the second period and probably should have wrapped the game up.
"We just all stick together as a group and work very hard together."
