Former LA Sparks GM Penny Toler says her firing in 2019 is complete B.S. ... and now she's suing the team claiming she was only axed because she complained about fellow executives' inappropriate behavior.
Remember, Toler was canned during last year's WNBA postseason ... after she used the n-word during what she claims was a pump-up locker room speech.
At the time, it was reported the Sparks had fired her over the speech ... but in a new lawsuit, obtained by TMZ Sports, Toler claims that wasn't the case at all.
Toler says the REAL reason she was 86'd has to do with complains she filed about multiple key personnel within the Sparks organization .
