The Seahawks made a roster move Saturday afternoon, placing linebacker Josh Forrest on injured reserve. No corresponding roster move was made, so Seattle could enter its Sunday Night Football matchup with the Philadelphia Eagles fielding 52 players on its active roster.
Forrest, who suffered what head coach Pete Carroll called a significant foot sprain in last week's win over the 49ers, was one of three injured players, along with safety Kam Chancellor (neck) and offensive lineman Oday Aboushi (shoulder), that the Seahawks had already declared out for their Week 13 game at CenturyLink Field. As a result of the transaction, if no addition is made to the roster Seattle will only need to declare six players inactive Sunday night, as opposed to the usual seven required for teams with 53 players.
The 6-foot-3, 249-pound Forrest was signed to Seattle's active roster from the practice squad in early November. A sixth-round pick out of Kentucky in 2016, Forrest, who spent his rookie season with the Los Angeles Rams, heads to IR having appeared in two games for the Seahawks. He originally signed to Seattle's practice squad in October.
The Seahawks vs Eagles matchup kicks off at 5:30 p.m. PT on Sunday, December 3 with national television coverage on NBC (channel 5 in Seattle).
Take a look back through history at the Seahawks' matchups against the 49ers as the two teams ready to face off for Sunday Night Football during Week 13 at CenturyLink Field.

Carson Wentz had five touchdown passes and no interceptions in helping the Eagles open with victories over Cleveland, Chicago and Pittsburgh. He has since been picked off 12 times compared to eight TD passes. That's only one reason why Philadelphia (5-8) has lost six of seven, including four in a row.
