OWINGS MILLS, Md. (AP) — Baltimore Ravens quarterback Lamar Jackson was not at practice Wednesday during the portion open to reporters.

The two-time MVP left last weekend’s loss at Kansas City with a hamstring injury, and by the end of that game, all four of Baltimore’s first-team All-Pros from last season were injured. The Ravens host Houston on Sunday.

Baltimore does have experienced backups in Cooper Rush, who started eight games for Dallas last season, and Tyler Huntley.

Also missing from practice Wednesday were: fullback Patrick Ricard, tackle Ronnie Stanley, linebacker Roquan Smith and cornerbacks Nate Wiggins, Chidobe Awuzie and Marlon Humphrey.
