As we previously reported, documents filed back in 2002 show there is a 99.9% chance that Pele Watkins is the father of James' 9-year-old son.
But in a letter dated August 1, 2009 -- and obtained by TMZ -- Watkins, writing from prison, tells James he never took a DNA test. At one point he wrote, "They will never get DNA from me."
He closes the letter, "I never took a DNA test but tell your mom I will fight her for messing wit [sic] me in jail."
We're told Devon will file the letter with the court in response to Tiger's motion to dismiss.
