Wicketkeeper Adam Rossington has had his Northants loan spell extended for a third time, keeping him at Wantage Road until the end of the season.
The 21-year-old has averaged 35 in both the County Championship Division One and One-Day Cup since arriving in July.
Northants have already announced all-rounders Andrew Hall and Matt Spriegel will leave at the end of the term.
Hall, who captained the side between 2010-12, has over 9,000 first-class runs for Northants in seven years.
The South African is the Division One side's leading wicket-taker, having taken 30 scalps, while 27-year-old Spiegel has made over 500 runs in 13 first-class games this year.
Last year's Division Two runners-up have struggled in the top tier, having lost 10 of their 12 matches and drawn the other two.
Rossington, on loan from Middlesex, hit 103 and 80 in his last first-class outing - a five-wicket defeat by Notts.
Northants are next in Championship action on Sunday when they face Somerset at Taunton.
