South Africa international leg-spinner Imran Tahir has played his last game for Nottinghamshire this season after picking up an upper thigh problem.
The 36-year-old was sidelined with the injury while on one-day international duty against New Zealand.
Tahir played three One-Day Cup games and one County Championship fixture for Notts following his arrival in July.
However, the club can still call on the services of Australian all-rounder Dan Christian in Tahir's absence.
"He was a popular member of the side," director of cricket Mick Newell told the Notts website.
"I'm sure the lads won't forget that should we go on and win the (One-Day Cup) competition."
