The Seahawks signed running back Tony Jones Jr. off the practice squad, adding extra running back depth with DeeJay Dallas listed as questionable for Saturday's playoff game due to an injury.
Nose tackle Isaiah Mack was waived to make room on the 53-man roster.
The Seahawks also elevated receiver Cade Johnson and linebacker Alexander Johnson from the practice squad for Saturday's game against the 49ers.
Jones, who was signed off the Saints' practice squad earlier this season, has appeared in four games for the Seahawks, seeing the most significant playing time in Seattle's Week 13 win over the Rams when he helped close out the game with Kenneth Walker III out with an ankle injury and Dallas playing through an ankle injury of his own.
Cade Johnson appeared in three games this season, recording his first two catches last week for 21 yards. Johnson saw significant playing time last week, playing 41 percent of Seattle's offensive snaps.
Alexander Johnson, a veteran linebacker who has made 34 career starts, signed to Seattle's practice squad earlier this season. Johnson was elevated for last week's game to give the Seahawks extra inside linebacker depth with Jordyn Brooks going on injured reserve, and recorded three tackles in his Seahawks debut while playing 16 snaps on defense and 17 on special teams.
The Seahawks claimed Mack off waivers last month with Al Woods dealing with an injury and Bryan Mone heading to injured reserve, but has been inactive for each of his two games with Seattle.
The Seahawks practiced on Wednesday, January 11 at the Virginia Mason Athletic Center in preparation for Saturday's Wild Card game vs. the 49ers in San Francisco. Seahawks practice photos are presented by Gatorade.
