Nahki Wells watched from the bench in this English FA Cup match as Jack Payne scored twice helping Huddersfield ended a run of six cup matches without a win with a 4-0 victory over Port Vale.
Payne, signed from Southend last summer, took his tally for the season to three with the first and last goals after Kasey Palmer and Harry Bunn also found the net.
Rai Simons started and was replaced in the 68th minute as Mark Marshall and Jordy Hiwula both scored for their second match in a row as Bradford extended their unbeaten run to six games with a 2-0 home win over Chesterfield.
The result secured their second double of the season and lifts them into fourth place in League One, level on points with Rochdale but above them on goal difference.
Reggie Lambe watched from the bench as Carlisle suffered back-to-back league defeats for the first time this season as a confident Colchester side extended their unbeaten run to eight games with four very well taken goals.
Carlisle United were defeated 4 - 1 by Colchester.
