Horford immediately sat down next to Brown to make sure his teammate knew he was there for him.
Thankfully, Brown started moving slowly as he regained consciousness and the former number three pick eventually was well enough to pick himself up and walk off the court to the applause of the crowd, who were glad to see the player well enough to leave of his own accord.
Brown, who walked off the court on his own, later left the arena to undergo a CT scan before rejoining the Celtics for the trip to the airport.
"We've just got to take advantage of the moments, continue to get better every game and utilize these games to really play our best", he said.
Kyrie Irving proved too much for the Timberwolves and finished with 23 points, eight assists and seven rebounds while shooting 9-of-15 from the field and carrying the offense at winning time. They have three more losses than the Raptors.

Nemanja Bjelica led all scorers with 30 points for the Timberwolves.
Towns notched a double-double with 15 points and 11 rebounds, while Wiggins added 13 points, but they were a combined 11-of-33 from the field and couldn't match Irving's spurt in crunch time.
The Wolves were within five at 88-83 in the fourth quarter, but every other time they were on the verge of cutting the margin to two possessions Irving and the Celtics had an answer on the other end.
Boston returns home to face the Indiana Pacers on Sunday night while the Timberwolves cap off a rough two-game stretch with a Sunday afternoon tilt against the Golden State Warriors.
