Notts Outlaws will have Conor McKerr available for the remainder of their T20 Blast group stage campaign after confirmation he will return to the club for a second loan stint from Surrey.
The 25-year-old played four matches for the club across May and June, taking four wickets.
And with Jack Brooks returning to Somerset following his short spell at Trent Bridge, McKerr has been enlisted for another spell.
"Both Conor and Jack have really bought into the way we want to go about things," said captain Steven Mullaney.
"Conor's a great guy, he's eager to learn, and we've made sure that his wife and little girl felt part of the group as well, with all the other wives and loved ones.

"The sign of a good environment is when people come in and don't want to leave, and hopefully we've got that here."
He will be available for the Outlaws' final five North Group matches, starting against Northamptonshire Steelbacks on Sunday (June 18).
McKerr has already spent part of the campaign at Kent, playing two County Championship Division One matches against Warwickshire and Essex.
In 61 appearances across formats for Notts, Derbyshire, Kent and Surrey, the South African has taken 98 wickets.
