The fine was also for two other offences in Friday night's game against the Thunders, the NBA announced on Saturday.
Rondo thrust his right knee into Schroder's groin area early in the fourth quarter of the contest and was called for a flagrant 2 foul.
In the aftermath, he verbally abused official Ed Malloy and failed to leave the court in a timely manner after being ejected, which the NBA cited was part of Rondo's fine.
Rondo expressed his displeasure prior to Saturday's game against the Memphis Grizzlies, saying the way Malloy pointed at him was "disrespectful".
"I guess the saying free speech doesn't apply to everybody," Rondo told reporters.
