Carlisle United are opening the Waterworks End for the first time this season for the visit of Derby County.

Home fans will be able to stand on the terrace for the September 23 clash at Brunton Park.

United are expecting a large attendance for the League One visit of the Rams.

Their decision to open the terrace to Blues supporters comes after United did so on occasions during last season's promotion run-in.

League games against Tranmere Rovers and Salford City saw the Waterworks open to Blues fans - along with the memorable play-off semi-final second leg against Bradford City.

Now United supporters will be on all four side of the ground again for the visit of manager Paul Simpson's former club.

"The Waterworks End (aka watterwuks) is open for HOME fans for the visit of @dcfcofficial  later this month," United tweeted.

"Get your tickets for that area and, of course, the other home areas, online here - let's get all four sides rammed (as they say)."

With Derby already having sold out their 1,546 allocation, the game looks set to attract Brunton Park's biggest crowd of the season so far.

United's home games against Fleetwood Town, Wigan Athletic, Exeter City and Shrewsbury Town have drawn attendances of 10,279, 8,649, 7,610 and 7,395 respectively.

Last season's decision to reopen the Waterworks End meant it was the first time Blues fans had stood on the terrace since 2009.

Derby, meanwhile, have advised travelling fans without a ticket not to travel to the game.
