The Seahawks made a handful of roster moves Saturday, placing safety Kam Chancellor on injured reserve, waiving offensive lineman Mark Glowinski, and promoting cornerback Mike Tyson and linebacker Kache Palacio from the practice squad to the 53-man roster.
Palacio, a second-year pro out of Washington State, brings some depth to the Seahawks' linebacker spot that could be without both Bobby Wagner (hamstring) and K.J. Wright (concussion) this Sunday against the Los Angeles Rams. Palacio was signed to Seattle's practice squad last month, while Tyson, a rookie out of Cincinnati, has spent the entire 2017 season on the practice squad.
Chancellor's move to IR doesn't come as a surprise. The team's starting strong safety suffered a neck injury during a game against the Arizona Cardinals in November and has been inactive ever since, with head coach Pete Carroll stating late last month that Chancellor would not return to action this season.
Glowinski, meanwhile, started the season as the Seahawks' first option at right guard. A fourth-round pick by Seattle in 2015 out of West Virginia, Glowinski was relegated to a backup role two games into the season and filled in on both sides of the line as needed, seeing action in nine games this year after starting all 16 regular-season matchups for the Seahawks in 2016.
