On Tuesday night, Grow was introduced on center court with his new teammates.
Before the game against the Cleveland Cavaliers, the teen was outfitted with his own custom jersey and a stall in the team's locker-room.
It was another memorable night for an inspirational young man.
The Sixers announced Monday they were signing the senior to a ceremonial two-day contract.
Signing the two-day contract capped an amazing week-long run in the national spotlight for the Bensalem High School senior.
Last week, Action News' Jeff Skversky reported on the 18-year-old whose story garnered attention from around the Delaware Valley.
"We said two minutes and you take advantage of your two minutes of fame. His life will be changed forever," said Earl Grow, father.
The teen, who has Down Syndrome, was the high school team's manager for the last four years.
Then, his coach let him suit up for the final two games of the season.
Grow scored three points in his debut game. The next day he scored 14 points, four of them were three pointers - including one right at the buzzer.
On Monday, the Sixers made Grow feel welcome to their team, even taking tips on their own three point shots.
"That's awesome. There's nothing like that really to see him out there, he's great," said Michael Carter-Williams.
His Bensalem teammates were also recognized at Tuesday's game.
"His teammates have been great throughout the four years. They've always included him. They mess around with him. They really make him feel like part of the team," said Dorothy Grow, mother.
