BOSTON (AP) — The Celtics say forward Gordon Hayward will be sidelined for around four weeks after suffering a severe ankle sprain in Boston's Game 1 victory over Philadelphia in their first-round playoff series.

The injury occurred in the fourth quarter of the Celtics' 109-101 win when Hayward went up for a rebound and rolled his right ankle as he landed on teammate Daniel Theis' foot.

With him out, it could mean a shift to a three-guard lineup and more minutes for Marcus Smart, who has been filling the role of Boston's sixth man.
