Agent: Brittney Griner Held Basketball Workout; WNBA Star Doing 'Really, Really Well'

Phoenix Mercury star center Brittney Griner dunked as part of a light basketball workout at Fort Sam Houston in San Antonio on Sunday and is doing "really, really well" after returning to the United States, agent Lindsay Kagawa Colas told ESPN's T.J. Quinn.

Colas said the seven-time WNBA All-Star hasn't decided if or when she will resume her career with Phoenix.

"If she wants to play, it will be for her to share. She has the holidays to rest and decide what's next without any pressure," Colas told Quinn. "She's doing really, really well. She seems to have endured this in pretty incredible ways."

Griner was detained in Russia for 294 days and had been serving a nine-year prison sentence for possession of hash oil.

The U.S. government considered Griner "wrongfully detained" and organized her release via a prisoner swap that freed international arms dealer Viktor Bout.

For now, Griner is staying at Fort Sam Houston with her wife, Cherelle, and has reunited with family as well. Per Colas, Griner should issue a statement "this week."
