Calvin Harrison has rejoined Northamptonshire on loan. 

The Nottinghamshire leg-spinner has taken 30 wickets in previous loan spells at Wantage Road this summer, while also recording his maiden First-class century. 

He made five appearances for in the Vitality Blast after returning to Trent Bridge, and took four wickets in Notts' home County Championship clash with Somerset. 

"Calvin's loan spells this summer have allowed him to enjoy an extended run of competitive cricket at a time when we have strength in depth in the spin department," said Head Coach Peter Moores. 

"The way he performed against Somerset is testament to the value of those loans, and this latest spell will mean he's ready to perform for us when needed towards the end of the season."
