The Lions play their third preseason game tonight as they host the Jacksonville Jaguars at Ford Field. Receiver Calvin Johnson is expected to make his 2014 debut tonight after sitting out exhibition games against Cleveland and Oakland. Johnson is coming back from offseason surgery on his knee and finger. Defensive end Ziggy Ansah may also see his first action of the preseason against Jacksonville. Ansah was activated from the physically unable to perform list last week, but was held out of last Friday's game against the Raiders. Ansah returns to the roster after having shoulder surgery at the end of last season.
