Carlisle City, based at Harraby Greyhound Stadium close to Gillford Park, were admitted to the Northern Rugby Football Union for the 1928–29 season.

Earlier in the season St Helens had visited Harraby Park on Sat 8 September and struggled to record a victory by 8 points to 5.

Mick Morgan replaced Agar and Carlisle made their debut in the First Division with a 7–10 home defeat against Wigan at Brunton Park.

New coach, Roy Lester, got rid of players based in West Yorkshire and recruited a team of Cumbrian amateurs.

They were then thrashed 112-0 by St Helens in a Lancashire Cup tie but recovered their season well, won more than they lost and finished in eighth place.

When a Rupert Murdoch funded Super League competition was proposed, part of the deal was that some traditional clubs would merge.

Their last league match on 20 July 1997, had produced a record score of 72–10 against another doomed side Prescot Panthers.

These players have either; received a Testimonial match, were international representatives before, or after, their time at Carlisle, or are notable outside of rugby league.
