Back injury sidelines Shane Carwin again, heavyweight seeks 2012 return to UFC

Onetime UFC title challenger Shane Carwin will have to wait a little longer to return to the win column.

The injury bug has struck yet again, and an ailing back has forced
Carwin to go under the knife and remain on the sidelines until spring or
summer of 2012.

Carwin announced his condition on his official website, Shane-Carwin.com.
