The Seahawks made roster moves Tuesday, promoting running back Troymaine Pope off the practice squad and signing former Saints defensive tackle John Jenkins. Running back Christine Michael and defensive tackle Sealver Siliga were waived to make room on the 53-man roster.

Pope first signed with Seattle as an undrafted rookie out of Jacksonville State, then was claimed off waivers by the New York Jets when the Seahawks made their roster cuts before the start of the season. Pope returned to Seattle earlier this month on the practice squad after being waived by the Jets. Pope emerged as something of a preseason star with the Seahawks, rushing for 162 yards on 24 carries, including an 86-yard performance against Minnesota in Seattle's second preseason game. He also scored the game-winning 2-point conversion in Seattle's preseason win at Kansas City.

Jenkins, 27, was selected in the third round of the 2013 draft by New Orleans, and in three-plus seasons he appeared in 49 games, starting 22. The 6-foot-3, 343-pound Jenkins started 12 games last season and had a career-high 49 tackles. Jenkins was released by New Orleans last week.

Michael was drafted by the Seahawks in the second-round of the 2013 draft, then traded to Dallas before the start of last season. Michael returned to Seattle late last season after short stints with Dallas and Washington, then re-signed with the Seahawks as a free agent in the offseason. Michael has started seven games this season, rushing for a team-leading 469 yards and 6 touchdowns on 117 carries, but over the past two weeks rookie running back C.J. Prosise has taken on a bigger role in the offense, including starting last week's game at New England. The Seahawks are also expecting to get Thomas Rawls back from injury this week, Seahawks coach Pete Carroll said Monday.
