The New Orleans Saints have lost linebacker Will Smith to a knee injury he suffered in Sunday’s game against the Texans, a source has confirmed to The Advocate. Pro Football Talk first reported the story Monday, citing an anonymous league source.

Smith left in the second quarter after being hurt on a play in which teammate Cameron Jordan sacked Texans quarterback Matt Schaub. He got tangled up with a couple of other players, was twisted to the ground and was taken to the locker room after being examined on the sideline.

Saints coach Sean Payton on Sunday said he had no update on the severity of the injury after the game. The Saints haven’t confirmed the report.

Smith is the second projected starter at outside linebacker for the Saints to be lost for the season to an injury. Victor Butler tore an anterior cruciate ligament during organized team activities in June.

Meanwhile, outside linebacker Junior Galette has been out since the second week of training camp with an undisclosed knee injury. Martez Wilson has also missed practice time with an elbow injury; though he’s returned to practice, he didn’t dress out for the Texans game.

Smith was the first-round pick for the Saints in 2004 and was moving from defensive end to outside linebacker in new defensive coordinator Rob Ryan’s 3-4 alignment.

Smith restructured his contract this past offseason, helping the Saints get under the $123 million salary cap. Check back later with as well as Tuesday’s edition of The Advocate for more information later.
