England spin coach Mushtaq Ahmed has agreed to join Surrey as a bowling coach and mentor on a month-long deal.
The 41-year-old former Pakistan international will join the county between June 20 and July 20, reuniting him with director of cricket Chris Adams, who he played with at Sussex.
Adams said on Surrey's website: "He will be a magic guy to have around in terms of the environment in the dressing room and is one of the best people I've ever come across in terms of assessing the mood of a side and having a positive influence on tactics both before and during a game.
"We have a few young spinners at the club at the moment so there is also plenty of work to be done there as well - and I also want to use him with the second XI and PG academy, as well as setting some sessions with batsmen from throughout the club on how to play spin."
While Mushtaq is with Surrey he will not miss any Test match action, with England playing a one-day series against Australia and West Indies.
