The board is yet to announce Sri Lanka's Test squad for the two matches.
Zimbabwe last played a Test match in November 2018 when they toured Bangladesh. The country was barred from ICC events in July last year because of political interference but was readmitted by the International Cricket Council three months later. Political turmoil within the sport and a string of humiliating performances led Zimbabwe to suspend their Test involvement in 2005, although they continued to play one-day internationals and Twenty20 internationals.
They returned to Test cricket in 2011 but are languishing in 11th place in the rankings, one ahead of Ireland.
