As for the mystery cornerbacks visiting the San Francisco 49ers today that we blogged about earlier, it turns out one of them was 10-year veteran Dre Bly. The 49ers moved quickly to replace the injured Walt Harris, signing Bly to a one-year contract on Thursday.

A day after the San Francisco 49ers confirmed CB Walt Harris tore a ligament in his right knee, coach Mike Singletary all but confirmed the 13-year veteran will be lost for the season “unless something else comes up.”

San Francisco 49ers CB Shawntae Spencer will have season-ending surgery on Wednesday to repair a torn ligament in his left knee.
