Levi Onwuzurike signed a one-year contract to stay with the Lions in free agency that included $2 million signing bonus and $1.5 million base salary.

Detroit Lions defensive lineman Levi Onwuzurike is out for the season after having knee surgery, and Taylor Decker and Josh Paschal are on the mend after surgeries of their own, coach Dan Campbell said.

Left tackle Taylor Decker is recovering from offseason shoulder surgery and will miss the Lions' first preseason game.
