It looks like Jennifer Garner isn't quite the superhuman ass kicking machine she plays on TV and in the movies. The star of the upcoming Elektra and TV's 'Alias' as been sidelined by "severe nerve damage," which occurred when a stunt went wrong on her TV show. Earlier reports had her sidelined with a viral infection and others even suggested she was pregnant with boyfriend Ben Affleck's baby. Due to the injury, Garner has had to cancel all promotional appearances for the new season of 'Alias', which started this week, and Elektra, which opens nationwide next Friday.
