Fynn Hudson-Prentice will join Sussex on loan ahead of the resumption of the LV= Insurance County Championship later this month.
The all-rounder will be available for Sussex’s fixtures against Worcestershire, Middlesex and Leicestershire, but not the team’s final match against his parent club, Derbyshire.
The loan precedes the 25-year-old’s permanent move to The 1st Central County Ground at the end of the season, which was announced last month.
