The Indian limited-overs squad, comprising 20 players and five nets bowlers, left for Sri Lanka on Monday and will reach Colombo after 4 pm.
"They will reach Colombo after 4pm and straightaway enter quarantine," confirmed an official from Sri Lanka Cricket (SLC).
The team, led by opener Shikhar Dhawan and coached by Rahul Dravid, will play three ODIs and three T20 Internationals next month.
"We will begin practice three days after arrival in Colombo," skipper Dhawan had told media on Sunday.
It means that the Indians will likely begin training latest by Friday, 11 days before the tour opening ODI on July 13th.
India also play ODIs on July 16th and 18th.
The ODI series will be followed by the T20 International series, with matches on July 21, 23 and 25.
"The key goal is to try and win the series. Hopefully, people can get opportunities to put up performances and knock on the doors of selectors," Dravid had said ahead of the departure to Sri Lanka.
