Four days removed from the Baltimore Ravens' season-opening loss, Lamar Jackson was not present Monday at their first practice of the week.
Ravens coach John Harbaugh was evasive when asked about Jackson and other players who were not participating.
"We had a number of guys that weren't out there. Some personal, some physical," Harbaugh told reporters. "Injury report comes out on Wednesday afternoon, so you'll be better advised on that day regarding all those guys."
Jackson played all 74 offensive snaps of Baltimore's 27-20 loss to the Kansas City Chiefs on Thursday night. The reigning MVP enjoyed a productive evening through the air and on the ground, throwing for 273 yards and a score on 26-of-41 passing and running for 122 yards on 16 carries.
Jackson missed a number of practices early in training camp with an illness. The star quarterback was not listed on Baltimore's injury report last week ahead of its season opener.
The Ravens (0-1) will be back at practice Wednesday, as Harbaugh pointed out to reporters, in preparation for their Week 2 home opener against the Las Vegas Raiders.
