NFL injury tracker: Latest injury news, fantasy implications for Week 5 as Lamar Jackson ruled out, Bucky Irving on crutches

Lamar Jackson, the Baltimore Ravens quarterback, has been officially ruled out for Week 5's game against the Houston Texans due to a hamstring injury that prevented him from practicing this week and kept him off the field during Friday's preparations.

Jackson sustained the injury during the previous Sunday's loss to the Chiefs, raising concerns that he could miss multiple weeks of play. With Jackson unavailable, Cooper Rush will start as quarterback for the Ravens in his place.

Several other Ravens players were also listed as did not practice on Friday, including safety Kyle Hamilton with a groin injury, linebacker Roquan Smith with a hamstring issue, cornerback Marlon Humphrey with a calf injury, and fullback Patrick Ricard with a calf problem.

The Ravens are aiming to avoid a 1-4 start to the season, which would be their first since 2015 when they finished 5-11 and missed the playoffs. After facing the Texans, the team will host the Los Angeles Rams before entering their bye week.

Other notable Week 5 injuries are mentioned in the report, though specific details are not provided in this segment.
