Randy Johnson has decided to undergo surgery on his back after consulting with Los Angeles-based specialist Robert Watkins. Johnson underwent a similar procedure in 1996.

Johnson pitched through September with a sore back, Johnson underwent an MRI late in the month and was diagnosed with a herniated disk. Watkins has concurred with the diagnosis, and a date for surgery should be set this week.
