The Seahawks signed the 36-year-old veteran Wednesday, about a week after he was released by the Tennessee Titans.
“Adrian had a good week,” Seahawks coach Pete Carroll said Friday. “It’s probably hard for people on the outside to understand the impact a guy with his kind of background can make. At a time where we’re battling to try to win a game and get going, he jumped in here and had a remarkable influence on the week.
“With three guys banged up at the spot, we’ll see how it goes on the weekend. He had a really productive week for us, and it was fun having him here.”
Running backs Rashaad Penny (hamstring) and Travis Homer (calf) were both full participants in Friday’s practice, while Alex Collins (abdomen) was a limited participant.
Peterson is the fifth-leading rusher in NFL history with 14,902 yards, including 82 yards on 27 carries in three games with the Titans.
The seven-time Pro Bowl selection and 2012 league MVP is fourth all-time with 119 career rushing touchdowns.
Seattle (3-8) brings a three-game losing streak into the NFC West clash with the 49ers (6-5).
