The following month he joined First Division Blackburn Rovers, where he made his first top flight appearances in April and May of 1931, playing left half for two matches and then four at centre forward, scoring twice in successive games against Middlesbrough and Sheffield Wednesday.
From October 1931 he broke into Rovers’ first eleven at left half, playing 29 matches before the end of the season, but the following season he soon lost his berth in the half back line before returning the the first team at inside left in a match against Blackpool in January 1932, scoring a hat-trick in a 6-5 victory at Ewood Park. However he soon lost his place, appearing only sporadically in the forward line during the rest of the season, scoring twice. His final match for Blackburn Rovers proved his only match of their 1933-34 campaign, when, playing centre forward, he scored in a 2-1 home win over Derby County in January 1934, joining Oldham Athletic in June 1934 after 9 goals in 48 appearances for Rovers.
He played just once for Oldham in September before joining Accrington Stanley in February 1935, scoring a hat-trick in a win over Gateshead in his third match, but left the club in the summer of 1935 after 9 goals in 12 appearances. After unsuccessful trials with Clapton Orient and Reading, he joined Aldershot in October 1935 and played once for them the following month, but moved on before the year end to Birmingham & District League club Worcester City. He then joined Hereford United in the 1936 close season, and played for Cradley Heath, Stourbridge and Evesham Town in 1937, later representing Worcester City in wartime football before his eventual retirement.
