Lamar Jackson was not at the portion of Ravens practice open to reporters on Monday.
The two-time and reigning MVP is coming off a 273-yard passing performance against the Kansas City Chiefs on Thursday. Jackson also ran the ball 16 times for 122 yards in the season opener.
Also missing from practice was cornerback Nate Wiggins, wide receiver Deonte Harty, and outside linebackers Kyle Van Noy and Adisa Isaac.
"We had a number of guys that weren't out there. Some personal, some physical," Head Coach John Harbaugh said. "Injury report comes out Wednesday afternoon, so you'll be better advised on that day regarding all those guys."
