Houston, TX (SportsNetwork.com) - Houston Texans outside linebacker Jadeveon Clowney's rookie season did not turn out as many expected.

The 2014 No. 1 overall draft pick will undergo surgery on his right knee and will be placed on season-ending injured reserve, the team announced on Thursday.

Clowney tore his meniscus in the knee during the season opener against Washington, then underwent surgery and didn't return to the field until Week 8 against Tennessee. The injury remained persistent, however, and the rookie wasn't able to regain full health.

The 21-year-old, who many thought would be a perfect compliment alongside stud defensive end J.J. Watt, totaled just seven tackles in four games this season.

"I think highly of all these players here," Texans coach Bill O'Brien said. "As it relates to JD, this guy's been injured and it's time to clean it up. This guy is a football player. He wants to play football, he wants to be good. He was disappointed."

O'Brien also noted that the team would like the surgery done as soon as possible so the rehab process can begin.
