Bonds has posted this on his website:
Sunday afternoon the doctor stopped by to give me the test results in regards to the fluid that was drained from my knee on Friday. I was told that I had a bacterial infection in my knee and I needed to have surgery immediately. I flew back to San Francisco Sunday night so I could make it to my appointment early Monday morning. The surgery went well. Dr. Ting cleaned out the infected area and they are now treating me with antibiotics.
My original plans were to wait a week before reporting on my condition so I would have a better idea on how my leg was responding. Due to informational leaks (I know who it is), the media has been contacting my PR firm asking about my status. So, before any hearsay or false information is reported, I wanted you to hear about my condition directly from me.
I know you have many questions regarding me playing baseball but right now I have to spend the time focusing on getting healthy. I've been through ups and downs before and I will be back.
As soon as I know more information, I will update you.
