Walker's upcoming procedure involves repairing a hernia, and the running back is targeting a return to full activity in time for Week 1, Ian Rapoport of NFL Network reports.
Per Rapoport, Walker wasn't dealing with what is sometimes called a "sports hernia" or core-muscle injury, but either way, the rookie looks like he has a chance to avoid missing any regular-season games. Once he's back to full strength, Walker will resume his quest to carve out a key early-season role in Seattle's backfield behind presumptive No. 1 option Rashaad Penny.
