BALTIMORE (WBFF) — Baltimore Ravens quarterback Lamar Jackson has been ruled out for Sunday’s game against the Los Angeles Rams.

Jackson ,28, suffered a hamstring injury during the game against the Kansas City Chiefs nearly two weeks ago. He left the game midway through the third quarter and did not return.

Jackson has not practiced at all in the last two weeks.

With Jackson sidelined, its expected that backup quarterback Cooper Rush would start again in his stead.

Rush, 31, started last week’s blowout 44-10 loss against the Houston Texans, and threw for 179 yards and three interceptions.

Through four games this season, Jackson has completed a career-high 71.6% of his passes for 869 yards and 10 touchdowns with just one interception, which came Sunday against the Chiefs. He has also rushed for 166 yards and a score on 21 carries.

With a bye week scheduled for Week 7, there’s a chance that Jackson could return to action on Oct. 26 against the Chicago Bears.

The Ravens will host the Rams at M&T Bank Stadium at 1 p.m. on Sunday.
