Sandra Bullock‘s walking “Speed” has taken a hit … the actress is sporting a pair of crutches after suffering an undisclosed injury.

The Oscar winner was spotted leaving a physical therapy session in Santa Monica Wednesday … leaning on a pair of crutches while walking with an aide to her car nearby.

The actress tried to keep a low profile … wearing a New York Yankees baseball cap and a gray sweatsuit to her appointment.

August has clearly been a tough month for SB. On top of her apparent health issues, August marked the one-year anniversary of her partner Bryan Randall‘s death.

As TMZ previously reported … the photographer died after a private battle with ALS on August 5, 2023. He was only 57.

Sandra — who turned 60 last month — previously described Bryan as the “love of [her] life” … sharing on an episode of “Red Table Talk” that they were raising their respective children together.

Sandra adopted her son Louis and daughter Laila outside her relationship with Bryan … and the photographer had a daughter from a previous relationship.

Despite her loss, Sandra is gearing up for a return to the spotlight … “Practical Magic 2” is currently in the works, with SB and Nicole Kidman returning to reprise their roles.
