Waege did not participate in Tuesday's practice due to a concussion, Matt Schneidman of The Athletic reports.
Waege recorded two tackles in Sunday's preseason game against the Broncos and played 35 snaps (32 on defense, three on special teams). It's unclear whether he sustained the injury in Sunday's contest, but he will now be sidelined until he clears the league's concussion protocols. That puts Waege's availability for Saturday's preseason finale against Baltimore in jeopardy.
