(Seattle, WA)  --  Delisa Lynch, the mother of Seahawks running back Marshawn Lynch, says she's not sure what the future holds for her son.  "Momma" Lynch was quoted by TMZ that her son still has gas left in the tank and will not retire.  But Ms. Lynch told KING-5 over the weekend that the report isn't true and that she doesn't know Marshawn's plans for the future.  Seahawks general manager John Schneider said last week he believes the star running back is "leaning toward retirement."
