Jim Boylan has filed a lawsuit against the Cleveland Cavaliers alleging age discrimination.

Boylan's contract was not renewed by the Cavaliers this offseason.

In court documents, he alleges he was informed of this by Tyronn Lue, who told him the decision came from general manager Koby Altman and team owner Dan Gilbert.

Altman, Gilbert, Cavaliers Holdings, LLC and Cavaliers Operating Company, LLC are each listed as defendants in the case.

Per the filing:

"On or about June 17, 2018, then Cavaliers Head Coach Tyronn Lue left Coach Boylan a voicemail, informing him his employment would end, in which Coach Lue said: “Jimbo, what’s up, yo? This is T Lue. I had a talk with Koby yesterday. He does not want to pick up your option. He said it’s way too much money. They’re not gonna pay that kind of money for three assistants on the bench. He wants to go younger in that position and, you know, find somebody who’s a grinder and younger in that position. And he said he does not want to pick the option up for I guess it’s 500 or - I’m not sure.

"He said five something. And he just said it’s too much money, he said, so we’ll be paying Longabardi and LD. So he just said he wanted to go younger at that position and he does not want to pick up the option.” “But give me a call back if you get a chance. If you don’t, I just want to thank you for everything and for everything you’ve given to me, stuff I’ve learned from you, helped me through all the situations, the health situations, and just being a young coach, man. You know, I hate to see this shit end like this, but I mean, I mean you try to (inaudible) to do this. Unbelievable, man. And so, you know, I just wanted to let you know that.” “So I’ll try to give you a call, but that’s kind of what Koby’s thinking is, and that’s kind of where Dan was at. And so I just wanted to, you know, give you a call, you know, to tell you that. I’m out of town right now to come and look at some places for myself for the center, but I’ll be back in town I think Friday or Saturday. So I wanted to let you know, man. I just want to say thank you; I love you, brother. And, yeah, honestly, if you need anything from me, you know, I’ll be right there to ask, I’ll be there to help you, man. So thank you."

The Cavaliers promoted 42-year-old Damon Jones in his place.
