1890-91 saw the second season of Tom Graham's captaincy and by Newport standards it was an average season. Newport played the whole season without star player Arthur Gould who had gone to the West Indies but the team of the future was being built. New faces included Tom Pook, A. E. Henshaw, Mat Hannan and W. Groves. Cardiff were beaten twice but Newport also lost twice to Cardiff. Incredibly Newport lost 4 times to Swansea. The only other defeat was at Devonport Albion.

Arthur Boucher played in all 27 games with T. England, Bert Gould, Charlie Thomas, Percy Phillips and T. Newcombe each missing just one game with 26 appearances. Charlie Thomas once again headed the scorers with 12t followed by George Thomas with 9t.

Newport United beat Swansea Harlequins in the final of the South Wales Challenge Cup at Rodney Parade by 6pts. to Nil. The Cup had been revived for junior and second teams and they also completed an invincible season with a record of P20 W19 D1 under captain W. E. Dowle. James Webbe, Fred Parfitt and Bert Dauncy all played for the United this season.

At least one other game would have been played as The Western Mail of 17th January 1891 reported:-

"RUGBY V NEWPORT MATCH OFF" - "On Friday afternoon Mr W. Clifford Phillips, Secretary of the Newport club, received a telegram from the secretary of the Rugby Football Club stating that his team refused to play to-day (Saturday) at Newport on account of the severe weather."

On 3rd January 1891 Wales played England at Rodney Parade losing by 3pts. to 7.
