The former player agent for San Antonio Spurs star forward Kawhi Leonard filed a complaint in a Florida federal court on Monday, suing his former agency for allegedly withholding payment on commissions he says he's owed, including on the $94.3 million contract that he negotiated for Leonard in 2015.

NBA agent Brian Elfus is suing Impact Sports Basketball LLC, its owner Mitchell Frankel, Impact -- A Sports Management Corp., and the company that bought out all of the Impact-branded sports agencies in 2016, J&S Sports Funding LLC, and its affiliated subsidiaries. Elfus is pursuing up to $5 million in damages against Impact Sports Basketball, Impact, J&S and its subsidiaries for allegedly failing to pay him commissions from Leonard and other clients.

Leonard hired Elfus in 2011 as he left San Diego State for the NBA draft. Elfus executed a four-year rookie deal with the Spurs worth $8.3 million before negotiating a five-year, $94.3 million deal for Leonard in 2015. Elfus represented Leonard until 2016.
