The Texans and Pro Bowl outside linebacker Jadeveon Clowney aren't in a major rush to get him back on the practice field.

Clowney isn't expected to return until training camp due to a knee injury that required arthroscopic surgery and has prompted him to seek a second medical opinion from Dr. James Andrews.

"I don't know," Texans coach Bill O'Brien said of when Clowney might return. "I wouldn't say he'll be in any OTAs, but probably training camp."

The star pass rusher and run stopper isn't medically cleared yet, but sources not authorized to speak publicly have emphasized that his long-term outlook is positive.

O'Brien downplayed any concern surrounding Clowney's health even though it's been four months since he underwent surgery.

"I think he's doing okay," O'Brien said. "He's in there with the medical team, trying to get better. He's in the meetings and things like that. I think he's progressing."

The former top overall draft pick expressed confidence in his knee.

"I'll be ready to go," Clowney said.

Entering his fifth NFL season and due a $12.306 million club option, Clowney is expected to eventually land a blockbuster contract extension this offseason.

However, no deal is imminent.

Both sides have expressed mutual desire to extend their business relationship on a long-term basis.
