Lamar Jackson hobbled out of the Baltimore Ravens' clash with the Kansas City Chiefs on Sunday night after suffering a hamstring injury late in the third quarter.
With the Ravens trailing 30-13 at Arrowhead Stadium, Jackson pulled up with the problem in the closing seconds of the third quarter and subsequently left the field.
After being replaced by Cooper Rush at quarterback and listed as questionable to return, the 28-year-old failed to return in the fourth and final quarter as Baltimore stared a third defeat of the season in the face.
They also lost cornerback Marlon Humphrey to a calf injury and lineback Roquan Smith to a hamstring injury in the first half against the Chiefs, leaving them without six defensive starters due to injuries. On the other side of the ball, left tackle Ronnie Stanley left with an ankle injury during the first quarter.
Before exiting the game Jackson completed 14 of his 20 passes for 147 yards, a touchdown and an interception. He also had six carries for 48 rushing yards in Kansas City.
It has been a disappointing start to the campaign for the Ravens, who already came unstuck against the Detroit Lions and the Buffalo Bills, meaning they will fall to 1-3 if they lose at Arrowhead as expected. Their only win so far came against the struggling Cleveland Browns.

Prior to Sunday's battle with the Chiefs, they were also forced to put defensive lineman Nnamdi Madubuike on injured reserve with a neck problem and defensive end Broderick Washington on IR with an ankle injury on Saturday.
And 90 minutes before kickoff, defensive tackle Travis Jones was made inactive with a knee injury and linebacker Kyle Van Noy was inactive with a hamstring injury.
Baltimore was also without cornerback Jaire Alexander, who has had a nagging knee injury and also was inactive.
Head coach John Harbaugh acknowledged this week that he was 'concerned' about Madubuike's injury, but hadn't been given the OK to discuss it. Madubuike has made consecutive Pro Bowls while starting every game the past two seasons.
