Burr-Kirven (knee) won't return to Saturday's preseason contest against the Broncos, Brady Henderson of ESPN.com reports.
Burr-Kirven has been a special-teams ace for the Seahawks during his first two years in the NFL, playing in all 16 games and registering eight tackles each season. The extent of the 23-year-old's injury is unknown, but if he is forced to miss time, Aaron Donkor will have an opportunity to carve out a backup role behind Jordyn Brooks.
