Baltimore Ravens quarterback Lamar Jackson may not play on Sunday against the Houston Texans due to his hamstring injury. Jamison Hensley of ESPN reported that Jackson did not practice on Thursday due to the injury, and it’s the second consecutive day he has missed practice. It was also revealed that safety Kyle Hamilton did not practice on Thursday due to a groin injury. Lamar Jackson suffered the injury in the Ravens’ 37-20 loss to the Kansas Chiefs last weekend. “Lamar’s working,” Harbaugh said, per ESPN.
