BOSTON - Curt Schilling, sidelined by shoulder weakness, has yet to be cleared to begin light throwing.

“He’s chomping at the bit to throw,” said manager Terry Francona, “but I don’t think Mike [Reinold, assistant trainer] believes [Schilling] is at a point where he can go out and throw.”

The Sox are being ultra-cautious with Schilling and don’t want him going backward.
