Lamar ruled out vs. Texans due to hamstring injury

Baltimore Ravens quarterback Lamar Jackson has been ruled out for Sunday's game against the Houston Texans due to a hamstring injury, the team announced Friday.

The star signal-caller suffered the injury in last week's loss to the Kansas City Chiefs. He exited the contest in the third quarter and didn't return. Jackson hasn't practiced this week leading up to Sunday's game.

Cooper Rush, who replaced the injured Jackson in Week 4, is slated to get the start, according to ESPN's Jamison Hensley. Rush has started 14 games during his eight-year NFL career. He signed a two-year deal with Baltimore this offseason after spending the last four seasons with the Dallas Cowboys.

More to come.
