Neighborhood media had hypothesized that the 37-year-old will just play three all the more home Tests - two in the progressing arrangement against Pakistan and one against India in August - before consummation his sparkling 15-year profession.
Yet, Mathews, identifying with journalists in front of the second Test against Pakistan beginning at the P. Sara Oval in Colombo on Thursday, said the group's senior master had still not decided.
"Kumar has still to affirm his retirement arranges," the Sri Lankan chief said. "He should meet the press throughout the most recent couple of days, however he has not done that yet.
"I know he is as yet conversing with the selectors."
Left-gave Sangakkara is the main current Test batsman. His 12,271 runs and 38 centuries far surpass second-put Alastair Cook of England, who has 9,000 runs and 27 hundreds.
The 131-Test veteran is unrealistic to make up for lost time with record-holder Sachin Tendulkar's Test count of 15,921 runs and 51 hundreds, however his 11 scores of 200 or more are only one shy of Australian legend Don Bradman's record of 12.
In the first Test against Pakistan in Galle, Sangakkara hit a 50 in the first innings - his 52nd half-century - and 18 in the second when Sri Lanka were shot out for 206.
Sangakkara had pounded 203 against New Zealand in Wellington in January, to proceed with a productive streak that saw him make 221 against Pakistan and 319 against Bangladesh a year ago.
Mathews denied that Sangakkara had deferred the declaration in light of Sri Lanka's staggering 10-wicket crush in Galle, which put Pakistan ahead in the three-match arrangement.
"He had been talking with the selectors even before the arrangement started," Mathews said, including the uncertainity had not influenced group spirit.
"I think Kumar has earned the privilege to choose when he ought to go," said Mathews. "He has served Sri Lanka well throughout the years and he will clearly be missed when he goes.
"In any case, it now up to the more youthful players to venture into the shoes of Kumar and Mahela (Jayawardene). It won't be simple however they have an incredible chance to make a name for themselves."
Jayawardene resigned from Tests and Twenty20 cricket a year ago and quit the one-day design after the late World Cup, where Sri Lanka made the quarter-finals.
Sangakkara took after his nearby companion and long-lasting buddy in stopping one-day and Twenty20 cricket in the meantime, yet stayed quick to play some more Test matches.
