(Renton, WA)  --  Seahawks star running back Marshawn Lynch is reportedly about to undergo surgery.  NFL Media's Ian Rapoport reports that Lynch will be out about a month and miss at least four of Seattle's final six games of the regular season.  Lynch met Monday with a specialist in Philadelphia about an injury to his abdomen.  He suffered the injury, which is described as a strain or tear of soft tissue in the abdomen, in practice before the Arizona game, and played through it against the Cardinals.
