Guitarist Jim Root will sit out Stone Sour's upcoming tour with Pop Evil in order to concentrate on writing the next Slipknot album.

"Everyone involved is okay with the decision, and our mutual friend Christian Martucci will be filling in on guitar," Stone Sour wrote in a statement.

"It was a difficult decision, but as the fans have wanted another Stone Sour tour, and Jim had responsibilities to the writing process with Slipknot, we feel this is the best decision where everyone wins."

The tour stops in Dallas February 13 at the House of Blues. Click here for more info.
