Injury by way of PlayStation 2

Joel Zumaya's post season injury was attributed to PlayStation 2. Zumaya had inflammation of the right wrist and forearm during the ALCS and was unable to pitch. After being checked out by team doctors and receiving treatment by the trainers, they were confused by the area and motion that caused the pain. Apparently, it was a guitar motion that caused the most pain. Zumaya was an avid Guitar Hero player at the time. After being instructed to stop playing video games, Zumaya experienced no pain during the World Series.

I can see this becoming a more popular injury in the future...especially with the new Wii system.
