It looks like Millie Bobby Brown is still trying to recover from that knee injury she recently suffered.

The 14-year-old actress was spotted in costume as Eleven on the set of Stranger Things on Monday (July 9) in Atlanta, Ga.

While Millie‘s co-star Sadie Sink was seen riding a bicycle through the rain for the scene, Millie had a stunt double fill in for her.

Over the weekend, Millie showed off her big smile on Instagram and gave an update on her injury. She wrote, “when your knee is nearly healed and you’re the happiest girl ☁️☁️.”
