The team on Thursday announced the release of the veteran offensive tackle, capping an injury-plagued final two seasons in Houston.
The 30-year-old Newton ruptured his patellar tendon in both knees during a Week 7 loss to the Broncos in 2016. He spent all of last season on the physically unable to perform list, but was hoping to make a return to action this offseason.
A seventh-round pick in 2011, Newton was selected by teammates as last year's Ed Block Courage Award winner. A versatile lineman who toiled at tackle and guard, Newton made 68 career starts for Houston between 2012 and 2016.
