Just before halftime in Toronto, Marcus Smart was coming off an Al Horford screen, slipped slightly, and immediately grabbed his left knee:

After trying to plant his left leg, he subsequently and apparently tweaks his right ankle.
Earlier in the game, Jaylen Brown was fighting for a defensive rebound and fell into Robert Williams’ knee. Williams continued to play and finished the first half with two points, four rebounds, a steal, and a block in 15+ minutes.
The team announced at halftime that both Smart (ankle) and Williams (left knee hyperextension) will not return to the game.

After Boston’s 106-104 win, head coach Joe Mazzulla said that keeping out Williams was strictly cautionary and x-rays on Smart’s ankle were negative.
