The Boston Celtics have had players suiting up in a total of 68 different jersey numbers (and have three others not part of any numerical series) since their founding at the dawn of the Basketball Association of America (BAA — the league that would become today’s NBA), worn by well over 500 players in the course of Celtics history.
To commemorate the players who wore those numbers, Celtics Wire is covering the entire history of jersey numbers and the players who sported them since the founding of the team.

With 25 of those jerseys now retired to honor some of the greatest Celtics to wear those jerseys, there is a lot of history to cover.

And for today’s article, we will continue with the second of two people to wear the No. 37, Boston forward alum Matt Ryan. After ending his college career at Chattanooga, Ryan would go unselected in the 2020 NBA Draft, instead playing in the G league before signing with the Celtics in 2022.
His stay with the team would span a single game, his tenure with the team coming to an end when he signed with the Los Angeles Lakers that same year.
During his time suiting up for the Celtics, Ryan wore only jersey No. 37 and put up 3.0 points per game.
