After playing below par against Portland and sitting out against Seattle, Francis is questionable with plantar fasciaitis against the Clippers on Sunday, according to the Houston Chronicle's Jonathan Feigen.  Kenny Thomas is also out with the same condition, though he would play in an emergency.  The Rockets third-string point guard, Tierre Brown, is on the injured list, leaving Moochie Norris as the starter and Cuttino Mobley, the starting shooting guard, as his backup.  Walt Williams filled in for Thomas in the Seattle game.
