The 1-3 Baltimore Ravens are expected to be without starting quarterback Lamar Jackson when they play the 1-3 Houston Texans at M&T Bank Stadium on Sunday. “Ravens quarterback Lamar Jackson is likely to miss Sunday’s game against the visiting Houston Texans with a hamstring injury, two sources with direct knowledge of the situation confirmed to The Baltimore Sun on Tuesday,” Wacker wrote. Following Sunday’s game, the Ravens play the Los Angeles Rams in Week 6, have a bye in Week 7, and host the Chicago Bears in Week 8. If Jackson cannot start, backup quarterback Cooper Rush is expected to get the nod against Houston. Baltimore could be in serious trouble if Jackson has to miss their contest against the 3-1 Rams in Week 6.
