Anderson had been suffering earlier in the week from an undisclosed but seemingly nasty illness, and was sent home from Valley Ranch, according to Tim MacMahon at ESPN Dallas, Monday, Tuesday and Wednesday, because the team feared he was contagious.
The fullback played through the illness in the win against New Orleans last Saturday at the Superdome with the help of an IV, which administered fluids to Anderson's body throughout; head coach Wade Phillips said Anderson was obviously affected by the mystery-affliction on the game film, however.
At any rate, this news is promising for Dallas. Aside from the fact that Anderson's an adroit fullback, his illness was such that it caused some personal concern among the team earlier in the week.
As of today, though, Anderson says all systems are go for Sunday at Washington.
"If I can do it in the eye of the storm," Anderson said in reference to the New Orleans game, "I'll be OK."
