Percy Harvin, who has played in just one game in his first year in Seattle, is unlikely to return to the field until the postseason begins in January, according to Pro Football Talk on NBCSports.com.
Harvin has not practiced fully since the lone game he played in this season, on Nov. 17 against his former team, the Minnesota Vikings.
In his five-year career, Harvin has only played in all 16 regular season games once. That was in 2011, according to SBNation.com.
While Harvin was expected to make a big impact on the passing game this season, the Seahawks have been fine without him, owning a 12-2 record which tops the league.
Seattle has two games left in the regular season, both of which are at CenturyLink Field. The Seahawks have won a franchise-record 14 consecutive games in Seattle.
Their remaining opponents are the Arizona Cardinals (9-5) and St. Louis Rams (6-8). The Seahawks beat both teams on the road earlier this year.
Harvin will continue to be listed on injury reports as week-to-week until he improves to day-to-day, according to head coach Pete Carroll.
