The Boston Celtics (7-1) defeated the San Antonio Spurs (5-4) in convincing fashion by way of a 135-115 decision on Saturday night. The win, the C’s seventh in a row, was head coach Brad Stevens’ first at AT&T Center and Boston’s first in San Antonio in eight years. But, the performance, which saw the Celts score a season-high 135 points, was overshadowed by an injury to Gordon Hayward late in the second quarter.

The injury occurred with 1:34 remaining in the first half when Hayward collided with LaMarcus Aldridge, who was whistled for an illegal screen on the play. The injury ended G’s night and sent him to the locker room for X-rays. The tests revealed a fractured left hand. Hayward recorded nine points, two rebounds and an assist in 15 minutes of work prior to the injury.

“Broken hand, no timeline,” Stevens said. “Going to the doctors tomorrow, and (they’ll) decide if he needs to do surgery or not. It sounds like, should he decide that, the surgery option might actually be a better timeline. So, we’ll see how that all plays out.”

The injury comes in the middle of No. 20’s most prolific stretch as a member of the Boston Celtics. Gordon entered Saturday’s matchup with San Antonio averaging 20.3 points, 7.9 rebounds and 4.6 assists per game for the season.

G-Time has already led the Celtics in scoring twice this season and in assists and rebounds three times each through the first seven games of the season. He entered Saturday’s contest ranked third in the league among high-volume wings (minimum 75 field goal attempts) in true shooting percentage, at 64.9 percent.

While Gordon will miss some time, Gordon and the Celtics are optimistic about his prospects for returning a little later on this season.

“This one doesn’t feel nearly as bad as it did two years ago,” said Stevens of the injury. “He’ll be back. He’ll be off for a few weeks or a month or whatever he is.”

With Hayward down, the C’s relied on and will continue to count on the Jayson Tatum, Jaylen Brown and Kemba Walker to keep their momentum rolling after completing a three-game sweep on their recent road trip. All three men have led the team in scoring at least once during the first seven games of the season.

Against the Spurs, it was Brown who picked up the scoring in Hayward’s absence. Brown led all scorers with 30 points (10-19 FG) in 32 minutes of action. He also accounted for seven boards and three assists. For Brown, the game marks the third time in his NBA career that he has hit the 30-point mark in a regular season game and the first such occasion of 2019.

Kemba tallied 26 points, eight assists and five boards, while Tatum went for 19 points, seven boards and four assists in the blowout win.

Additionally, second-year man Robert Williams had a career-high 6 blocks tonight. That’s also tied for the most blocks in a game this season by an NBA player.

The C’s will look to extend their win streak on Monday night when they return home to TD Garden to face Luka Doncic and the Dallas Mavericks (6-3). Tip-off is at 7:30 p.m. ET.
