Mason Crane is set to miss Hampshire's inaugural day-night Specsavers County Championship match after being included in the England Lions squad for next week's three-day tour match against South Africa.

Crane and the seven batsmen are available for their counties for the first two days but with Liam Dawson available Hampshire are expected to go with the slow left-armer as their main spinner against Somerset on Monday (2pm start).

The Lions' clash at New Road, beginning on June 29, is the Proteas' only first-class match before their four-Test series against England gets under way the following week at Lord's.

Captain Gary Ballance - as well as Sam Robson, Keaton Jennings, Joe Clarke, Liam Livingstone and Tom Westley - could therefore enhance their respective cases for senior recognition with a strong showing against the tourists.

The four pace bowlers in the squad - George Garton, Saqib Mahmood, Jamie Overton and Tom Helm - will be rested from the championship's day-night round, beginning next Monday.

England Lions squad: G Ballance (captain), S Billings (wkt), J Clarke, M Crane, G Garton, T Helm, K Jennings, L Livingstone, S Mahmood, J Overton, S Robson, T Westley.
