Riquna Williams, right, faces burglary and aggravated assault charges in connection with the December 6 incident.
The Sparks are 5-1 with Williams in the starting lineup, and she's averaging 11.5 points and 2.7 assists in 15 games this season.
Williams' criminal case is still ongoing. "The WNBA will also require Williams to participate in counseling", the league said in a statement.
If Williams does not appeal her suspension, the punishment will take effect beginning with Thursday's game against the Dallas Wings.
The WNBA said it had considered "the nature and seriousness of the conduct at issue, including the involvement of a firearm" in determining the suspension length.
"The Sparks have cooperated fully with the league's investigation", it read, in part.
According to Williams' agent, Orlando Castaño, the league had been seeking to suspend Williams utilizing Article XIV of the WNBA's Collective Bargaining Agreement, Player Conduct and Discipline. "We are immediately filing a grievance and will seek the arbitrator's review". "We will provide whatever resources we are allowed to help Riquna learn and grow from this unfortunate situation".
The story behind the arrest is insane - Williams allegedly showed up at her ex's Florida home, destroyed her vehicle with a skateboard, forced her way into the house, hit her in the head several times and pulled her hair out. According to police records, Williams went to her auto after the altercation, placed a firearm on the trunk, pointed it at a bystander and said "you'll get all 18" before fleeing the scene.
Assuming she doesn't appeal, Williams would return for the Sparks' final eight games, starting against the Indiana Fever on August 22.
The suspension surpassed the seven games given to Brittney Griner and Glory Johnson in 2015 for their domestic violence arrests. Then, Williams allegedly returned to her vehicle and brandished a firearm, pointing the weapon in the direction of a third party and uttering a threat before driving away.
