Former Penn State coach Bill O'Brien was introduced Friday as the third head coach in Houston Texans history.
Less than two years after replacing Joe Paterno, the 44-year-old O'Brien has returned to the NFL. He was an offensive assistant under Bill Belichick at New England from 2007-12.
O'Brien takes over for Gary Kubiak, who was fired with three games left in Houston's NFL-worst 2-14 season.
O'Brien was 15-9 at Penn State, hit hard by NCAA sanctions levied for the Jerry Sandusky child sex abuse scandal that cost the late Paterno his job. Despite a lack of scholarships, a bowl ban, an overall sense of doom and player defections, O'Brien led the Nittany Lions to two winning seasons.
Penn State named defensive line coach Larry Johnson as interim head coach while the search for a replacement begins.
