Gordon Hayward, the Boston Celtics forward, has reportedly agreed to a “massive shoe deal” with Chinese sportswear brand Anta, according to ESPN.

The four-year deal includes a signature apparel collection. Anta last year signed a 10-year deal with Warriors guard Klay Thompso, and it also counts Lakers guard Rajon Rondo as an endorser. With more than 9,000 stores throughout Asia, Hayward’s collection will be marketed in both Asia and the U.S.

Nike, Hayward’s sponsor since he began his NBA career, will have 10 business days to exercise a “match clause” in its contract.
