The money fight between UConn and former men’s basketball coach Kevin Ollie is getting messy.

ESPN reports that Ollie’s lawyers have sent a letter to UConn, accusing the school of violating his constitutional rights by firing him for ‘just cause,’ before giving him a chance to fight the decision.

So far, there has been no comment from UConn. 

At stake is the more than $10 million left on Ollie’s contract, which runs through 2021.

Ollie was fired on March 10, after the school cited an NCAA inquiry into potential violations as the reason for firing him. 

He says he was entitled to a letter outlining the reasons for his firing, but he never got one. 

UConn’s on-court performance declined sharply after Ollie coached the program to a stunning national championship in 2014. 

The Huskies finished with losing records in the last two seasons, the first time that had happened since 1985-87.

Connecticut hired former Rhode Island coach Dan Hurley as Ollie’s replacement, signing him to a six-year deal worth about $3 million per year.
