Conor McKerr has returned to Notts Outlaws on a two-week Vitality Blast loan deal.
The Surrey seamer took four wickets for the Outlaws in four T20 appearances earlier this summer, and returns as Notts enter the final fortnight of their Blast group-stage campaign.
In total, the 25-year-old has taken 98 wickets across 61 appearances for Notts, Derbyshire and Surrey.
Jack Brooks, meanwhile, has returned to Somerset.
