Estimated Reading Time: 2 minutes

When the Oklahoma City Thunder played the Minnesota Timberwolves towards the end of 2019, Chris Paul lobbied the referee to issue a delay of play violation against the Timberwolves. This then resulted in a technical foul against the Timberwolves, due to the untucked jersey being a second delay in play violation. In turn the Thunder recieved a free throw in a game that was to close to call. It made me wonder how many people know why do NBA players have to keep their jersey tucked in?

Why do NBA players have to keep their jerseys tucked in? If a player has their jersey untucked as they enter the court of play then under NBA rules this is deemed as a delay in play violation. If the violation is committed for a second time then a technical foul is awarded to the opposition.

In this article, we look at what the rule is, whether anyone has been fined for an untucked jersey and how NBA players stop their shirts from being untucked. If you have not seen what happened with Chris Paul you can check out the video below.

Therefore, having a jersey untucked constitutes as not being ready to appear on the court. Due to this a NBA team is deemed to have a delayed a game, if it is the first time in a game then the team is given a warning. However, if a delay in game happens again a team is given a technical foul against them. This results in an opposition team being awarded a free throw for the technical foul.

Has anyone been fined for an untucked jersey?

We could not find anyone who had been fined for persistently having their jersey untucked. However, we did find two instance of players fined for removing their jerseys prior to leaving the court. The first instance was in 2006, Udonis Haslem was fined $5,000 for removing his jersey as he left the court and the second instance was in 2011 when Andrew Bynum was fined $25,000 for removing his jersey as he left the court. With fines like those it is obvious why players keep their kit in check.

How do NBA players keep their jerseys tucked in?

When the rule was brought into force Adidas made the NBA kits. However, an untucked jersey was a persistent problem and given the movement made on a basketball court, a jersey would always be untucked. Therefore, Adidas put silicone in the waistband of the basketball shorts in order to keep the jersey tucked in for the entire game.

Now Nike produce the NBA Team uniforms the silicone still remains in the basketball shorts to ensure that a untucked basketball jersey does not happen. Below is an image of the silicone within the shorts.

A basketball court was built in my local park and at 15 years of age I fell in love with basketball. A late joiner to the game, I have played every season since. Some Indiana friends bought me some Pacers gear for my 17th birthday, and I have supported them ever since (who wants to follow the crowd). I love American sports apparel and the presentation of sports, they do it so well (bar all the advert breaks).
