Marcus Smart will miss at least the rest of the regular season after undergoing thumb surgery Friday, Adrian Wojnarowski reported Friday morning.
Reportedly, the surgery is to repair a torn ligament in Smart's right thumb.
Smart's injury has been one of many for the C's of late. In addition to Gordon Hayward likely being done for the season, the Celtics were without Kyrie Irving, Al Horford, Jaylen Brown and Smart in Wednesday's loss to the Wizards.
The playoffs begin April 14. ESPN's Chris Forsberg reports that sources told him that with a six-week timetable for recovery from surgery, the hope is Smart could return sometime in the playoffs.
Horford is expected to play Friday against the Magic after missing the past two games due to an illness.
