Akila Dananjaya was called up to Sri Lanka's ODI squad to face South Africa after his bowling action was deemed legal by the International Cricket Council.
His remodeled bowling action was assessed in Chennai on February 2, where it was found the amount of elbow extension for all his deliveries was within the permissible 15-degree level of tolerance.
Dananjaya was reported over a suspect bowling action during the first Test of the England series in Sri Lanka in November and was banned after an independent assessment of his bowling action in Brisbane on November 23 revealed his deliveries exceeded the 15-degrees level of tolerance permitted under the regulations.
Sri Lanka also brought in three uncapped players to a 17-member squad for the five-match one-day international series against South Africa.
Debutant right-hand batsman Oshada Fernando was among those named for the series, which starts on March 3.
The other two newcomers include bowler Kamindu Mendis, 20, and all-rounder Priyamal Perera, 23.
