Walker suffered an abdominal injury in the fourth quarter of Sunday's 26-20 win over the Broncos.
Walker was subbed out late in the fourth quarter due to abdominal pain. Prior to the injury, he rushed 20 times for 103 yards and a touchdown while adding two catches for six yards on three targets. In addition to scoring a 23-yard touchdown in the third quarter, Walker had a would-be six-yard touchdown nullified by a holding penalty on the following drive. Walker's practice participation will be worth monitoring as the Seahawks prepare to face the Patriots in Week 2.
