With OTAs wrapping up and the Texans facing a cutdown to 80 players before training camp, Kubiak still doesn't know if offensive tackle Charles Spencer will be able to participate for the 2008 season. Even with medical clearance on the knee, Spencer has an uphill battle to make this team. His best chance would be a position change to Guard. But if Spencer can't go during OTAs, the Texans can't assume he'll be ready to go by training camp and cut a player who can contribute. Spencer's short career with the Texans could be coming to an end.
