Every player in Boston Celtics history who wore No. 50

This is every player in Boston’s history who wore the Celtics’ No. 50 jersey for at least one game as of Aug. 2023.

The Boston Celtics have more retired jerseys than any other team in the NBA, but that doesn’t mean the rest of their jerseys have little history of interest tied to them.

In fact, with 17 titles to their name and decades of competitive basketball played in them, their unretired jersey numbers pack in some of the most history not hanging from the rafters of any team in the league. To that end, we have launched our accounting of that history, with every player in every jersey worn by more than one Celtics player in the storied franchise’s history accounted for.

Today’s installment focuses on the eight players who wore No. 50 over the years as of Aug. 2023.

Explaining the NBA’s hardship exception and the free agents who signed as replacement players

Explaining what hardship exceptions and replacement players mean as COVID-19 protocols hit the NBA.

As the omicron variant of COVID-19 continues to spread, the NBA has required a large share of “replacement players” to fill in for the players who are in health and safety protocols. And so far, more than 100 players have reportedly entered the league’s health and safety protocols so far this month, per ESPN’s Baxter Holmes.

But how exactly do the “replacement players” work?

Essentially, the NBA’s hardship exception allows teams to exceed the 15-man roster limit if more than three players on the roster are each going to miss extended time due to illness or injury. Typically, teams weren’t allowed to apply for the hardship exception before Jan. 5.

But starting last season, the league changed the policy to allow earlier exceptions. And as of earlier this week, effective Dec. 19 until Jan. 19, the NBA is allowing teams to sign one replacement player for each player on their roster who tests positive for COVID-19.

While there are some big names (e.g. Isaiah Thomas, Lance Stephenson, CJ Miles) who have signed as replacement players, there are lots of promising young NBA hopefuls who are hoping to use this opportunity as a chance to stick around the league.

Not all of the players below were signed through hardship exceptions and some transactions (e.g. DeMarcus Cousins and Wesley Matthews to the Milwaukee Bucks) may have happened anyway during a normal season.

But below, based on the NBA’s transaction log and reporting from the league’s top insiders, you can find a live tracker of all the players who have signed new deals with NBA teams over the course of the past month.
