The 27-year-old fast bowler failed to make the original one-day squad but was included at the request of team managers. Tanvir replaced opener Nasir Jamshed who suffered a finger injury before the tour began.

Tanvir was declared man of the two-match Twenty20 series which Pakistan levelled on Sunday with a thumping 23-run win in Hambantota. Sri Lanka won the first match, also in Hambantota, on Friday by 37 runs.

Chief selector Iqbal Qasim confirmed Tanvir's inclusion.

"In view of the request from the team management and keeping in consideration the current form of Tanvir, the selection committee has decided that he may be retained for the one-day series in Sri Lanka," Qasim said in a Pakistan Cricket Board statement.

Pakistan and Sri Lanka play the first of five one-day matches at Pallekele on Thursday. The one-days will be followed by three Tests.

Tanvir has 55 wickets in 43 one-day games.
