Duo called up by Northern Ireland
The strike duo have been added to Michael O'Neill's squad for the games against Uruguay on May 30 and Chile on June 4 after the withdrawals of fellow forwards Martin Paterson and Jamie Ward earlier this week.
Gray, a regular in the Under-21 set-up, and wins a first call-up to the senior set-up while Boyce returns following a three-year absence.
The 23-year-old was capped under previous boss Nigel Worthington at a time when he was contracted to Werder Bremen, but now becomes the only Irish League player in O'Neill's 23-man squad.
Boyce has been prolific for Cliftonville since returning to Belfast from Germany, helping the Reds to successive league titles and catching O'Neill's eye in the process.
