Former legendary Sri Lanka skipper Kumar Sangakkara says he will retire from first-class cricket after this season.
The former Kings XI Punjab batsman, who quit Test cricket in 2015, is fifth in the list of all-time Test run scorers.
"You try to fight the inevitable but you need to get out while you're ahead," the 39-year-old told BBC Sport.
"It's the last time I'll play a four-day game here [at Lord's]. I'll be 40 in a few months, this is about the end of my time in county cricket."
The Surrey batsaman Sangakkara has contracts to honour in Twenty20 competitions taking him into 2018, but added: "My career might have a few more months [left] but that's about it."
The Hobart Hurricanes batsman averaged more than 57 runs across 134 Tests, making 11 double hundreds in that time, and joined Surrey for the 2015 season.
The former Durham batsman scored more than 1,000 first-class runs last season but, despite hitting two hundreds versus Middlesex over the weekend, He believes September is the right time to end his career in the longer format.
"The biggest mistake that sometimes you can make is that you think you're better than you really are," Sangakkara said.
"Cricketers, or any sort of sportsperson, have an expiry date and you need to walk away.
"I have been very lucky to play for as long as I did so but there's a lot more life to be lived away from the game."
"It was a great privilege and an honour. I think the artist has made me look better than I actually am," the veteran cricketer joked.
"I sat here in my last Test at Lord's for Sri Lanka thinking 'I hope I get a hundred, but wouldn't it be funny if I get out for a duck'.
"You never think of [scoring a] hundred. You think 'I want to get a hundred', but then you just try and do your processes, you try and get through tough periods, and bat as the game develops.
"I wasn't aware I'd reached 20,000 [first-class] runs - I only really know how many Test and One-Day International runs I've scored - but it was really nice to find out that I passed [that milestone].”
