Sri Lanka announced four new coaching staff Sunday to assist new head coach Chris Silverwood ahead of next month's two-match Test series in Bangladesh.

Former Sri Lankan Test player Naveed Nawaz was named assistant coach for a two-year period, Sri Lanka Cricket said in a statement.

Nawaz had been the head coach of the Bangladesh junior team which won the Under 19 World Cup in 2020.

The cricket board also announced specialist coaches Chaminda Vaas for fast bowling, Piyal Wijetunge for spin and Manoj Abeywickrama for fielding.

The first Test begins May 15 in Chittagong, followed by a Dhaka fixture from May 23.
