(Undated)  --  Several reports are circulating that former Seahawks running back Marshawn Lynch may renounce his retirement.  Lynch, who retired after the end of last season, is currently "up in the air" about coming back, according to Mike Florio of "Pro Football Talk."  The Seahawks still hold Lynch's rights and have him placed on the reserve-retired list.  Florio quotes a source as saying Lynch could be back on the field as early as Week 4 or 5.
