The Packers list Valentine (ankle) as doubtful for Sunday's game against the Titans, Matt Schneidman of The Athletic reports.
Valentine's defensive participation spiked to 57 percent of the team's defensive snaps last week against the Colts after being on the field for just 12 percent of the defensive plays versus Philly in Week 1. Eric Stokes will have to take on a larger role alongside Jaire Alexander and Keisean Nixon at cornerback for Green Bay if Valentine is absent Sunday as expected.
