Valdes-Scantling was unavailable for Thursday's preseason finale against the Packers because he was in concussion protocol, Adam Teicher of ESPN.com reports.
Valdes-Scantling was present on the sideline but was not in pads. The injury shouldn't raise too much concern in terms of Valdes-Scantlling's availability for Week 1, as he still has around 17 days to clear the necessary protocols. He also got some time this preseason to mesh with Patrick Mahomes, as he caught a total of three passes for 35 yards across the team's first two preseason contests.
