Houston Texans outside linebacker Jadeveon Clowney returned to action last week after missing six games with a knee injury, but he might be sidelined again for Sunday’s game against the Philadelphia Eagles.

“I don’t know,” Texans coach Bill O’Brien said Friday regarding Clowney’s status. “I wouldn’t say it looks very good for him playing Sunday.”

O’Brien said Clowney’s playing status would be a game-time decision.

The problem is not the torn meniscus that Clowney suffered in the first game, forcing him to miss the next six games.

Apparently the problem now is that Clowney is ill, and the sickness has drained Clowney to the extent that the Texans are not sure whether he will be at full strength by Sunday.

Clowney was the No. 1 overall pick in this year’s NFL Draft.
