SEATTLE — Earl Thomas got a brief look at Percy Harvin during offseason workouts. He saw his skill in a Minnesota uniform the previous four seasons.

And Seattle’s star safety certainly knows what Harvin can do in the virtual world.

“I do so much with him in Madden, I’m just excited to see what he can do out here,” Thomas said. “That dude is a game changer.”

Harvin may finally make his long-awaited and delayed debut for the Seahawks on Sunday when they go for a 13th straight home win hosting Minnesota. Ever since Harvin underwent surgery to repair the labrum in his hip on Aug. 1, the date of Nov. 17 has been watched as a possible return for the dynamic wide receiver. With the added incentive of that potential debut coming against his former team.

Harvin was added to the 53-man roster earlier this week. Coach Pete Carroll has cautioned they won’t rush Harvin’s return. Ask around, though, and most expect Harvin to play.

Aside from Harvin’s potential debut, the game also features two of the best running backs in the NFL in Minnesota’s Adrian Peterson and Seattle’s Marshawn Lynch. Their running styles are uniquely different — Peterson more of a speedy glider, Lynch runs choppier — but the end result is consistently chunks of yards being collected.

Lynch enters the week No. 2 in the NFL in yards rushing behind Philadelphia’s LeSean McCoy. Peterson is No. 4. Both are coming off big games. Lynch ran for a season-high 145 yards last week against Atlanta, while Peterson had two TDs rushing against Washington.

“They have so many things that they can do so uniquely, but they are different and they both have a really definitive style,” Carroll said. “Marshawn’s way of running and Adrian’s way of running, they’re not at all the same but they’re extraordinary players and really fun to watch.”
