[6] In 1886 Shacklock rejoined Nottinghamshire and played 117 matches for them over the next eight years, taking 360 wickets at an average of 18.74 and a best performance of 8 for 32 against MCC in 1887.
[9] Following his suspension by Nottinghamshire he began a career as a professional in the Lancashire League, playing initially for Nelson Cricket Club for three seasons.
[6] He also worked coaching cricket, including at Solihull Grammar School in Birmingham and at Clongowes Wood College in County Kildare.
[9][10][11] In 1903 Shacklock moved to New Zealand, where he was employed as a coach in Dunedin[12] and played four first-class matches for Otago as well as one in 1903–04 for a South Island side.
In his obituary, published in the 1938 edition of the Almanack, his bowling was described as having been "considered particularly difficult because of this pronounced swerve from leg" which he "varied with an off-break that came very quickly from the turf".
[3][6] Arthur Conan Doyle is believed to have used a combination of Shacklock and Sherwin to name his most famous character, Sherlock Holmes.
