EDEN PRAIRIE, Minn. — Vikings coach Brad Childress is planning on Pro Bowl defensive tackles Kevin Williams and Pat Williams playing in Sunday's game against Houston.

Childress had no comment Monday on a Fox Sports report that the two Williamses have tested positive for one of the NFL's banned substances. That would mean a four-game suspension pending appeal.

The league's policy is supposed to be confidential, so coaches and the NFL cannot comment.

Childress called the situation "a personal issue." He says the Vikings won't let it be a distraction.
