Dee For underwent extensive knee surgery following Super Bowl LIV.

Dr. James Andrew underwent the surgery on Ford's left knee.

"We were spot-on with the injury as far as diagnosing it in training camp," Ford said. "I had a severe case of tendinitis. ... With my position, that's a blown tire. I feel great right now. I'm able to actually explode off of this knee. Thinking back on it, I can't believe I played a whole season on it, and we knew at the end of the day what we had to do. It had to be surgical, but I didn't want to miss the season. We had too much going on. I didn't want to miss that. It's in the bag now, though, I'm confident in that."

Ford has said the knee (and corresponding quadriceps issue) plagued him for many of his previous six seasons in the NFL -- perhaps never more so than last season, his first in San Francisco.
