Pakistan spinner Abdur Rehman has been handed a 12-week ban by the England and Wales Cricket Board after testing positive for cannabis during his 2012 spell at Somerset.
Rehman enjoyed a hugely successful spell at the County Ground this summer, taking 27 LV= County Championship wickets at an average of 14.19.
But the 32-year-old failed a drugs test following day two of Somerset's County Championship game with Nottinghamshire on August 8.
Rehman's suspension will run until midnight on Friday, December 21.
Somerset chief executive Guy Lavender said: “Somerset County Cricket Club fully supports the action taken by the ECB.
"The club does not condone the use of illegal drugs in any circumstances and all Somerset players are made fully aware of this policy on a regular basis.”
Rehman issued an apology in a statement released this afternoon by Somerset.
“I apologise to my family, the PCB, the ECB, Somerset County Cricket club, my teammates and my fans," he said.
“It was an error of judgement on my part that will cost me dearly and I would like it to be a lesson to all others in sports and elsewhere.
“I will do my best to stay fit and focused during my suspension and god-willing will be available for selection for the India series should the PCB see it fit for me to be selected.”
