Whether or not Jadeveon Clowney plays on Monday Night Football against Pittsburgh is still up in the air.
Bill O'Brien was asked after Wednesday's practice if he had a better feel about the rookie's readiness, and responded with "no".
Clowney had knee surgery in early September after he left the Week 1 win over Washington in the first half.
Earlier in the week on his radio show, O'Brien said the chances Clowney would suit up against the Steelers were still "50/50".
Defensive end J.J. Watt said he welcomed the return of Clowney to the lineup, whenever that happens.
"Obviously we'd love to have all of our players out there and healthy and ready to go," Watt said. "But we'll see."
Third-year outside linebacker Whitney Mercilus has started in place of Clowney since Week 2. Mercilus has six quarterback hits and three tackles for loss on the season.
