Jerome Jayaratne, Sri Lanka Cricket (SLC) head bowling coach, said that the off-spinner has corrected his action since being banned by the ICC.
The SLC executive committee, convinced now of the correctness of Senanayake's bowling action, has approved the off-spinner's departure for testing at Chennai's Sri Ramachandra University, Jayaratne added.
In August, Senanayake underwent correction programme to remodel his bowling action at the University of Westen Australia in Perth.
He was suspended by the ICC mid July following tests conducted at the Cardiff University in England.
