Tyler Huntley would start for the Ravens if Lamar Jackson cannot play, per multiple reports. Jackson suffered a sprained ankle in the first half of Sunday's victory over the Titans and did not return for the second half.
Per Sportsnet's reporting of NFL insider Ian Rapoport, Jackson is "unlikely" to face the Falcons this Sunday, though his injury is not considered long-term or surgical. Rapoport also indicated that Jackson could miss multiple weeks depending on how his rehabilitation progresses, per NFL Trade Rumors. The exact Week 5 status remains unknown across the reporting, with multiple outlets describing Jackson's availability as an "outside chance" rather than a likely outcome.
