Lynch was at the team's facility earlier this week and coach Pete Carroll said on Friday that it will be ''week-to-week'' regarding when Lynch might rejoin practice.
''We'll see what happens next week,'' Carroll said.
Lynch underwent surgery on Nov. 25 for an injury related to a sports hernia. He played through it in Week 10 against Arizona, then sat out the following week versus San Francisco.
Between the surgery and a hamstring injury earlier in the season Lynch has missed 5 1/2 games. Rookie Thomas Rawls has filled in for Lynch and is on pace for a 1,000-yard season, averaging 5.6 yards per carry.
Carroll also said tight end Jimmy Graham has rejoined the team following surgery to repair a torn patellar tendon suffered in Week 12 vs. Pittsburgh.
The Seahawks are 7-5 and in contention for a wild-card spot.
