Tyler Huntley, who played the second half against the Titans in place of Jackson, was joined on the practice field by third-string rookie quarterback Joe Fagnano.
The Ravens had seven players who didn’t practice Wednesday, as Jackson was joined by cornerback Marlon Humphrey (hamstring/calf), left tackle Ronnie Stanley (NIR-rest/toe/ankle), outside linebacker Trey Hendrickson (finger), defensive lineman Calais Campbell (NIR-rest), guard Andrew Vorhees (foot), and tight end Durham Smythe (Achilles).
Smythe has been placed on injured reserve. However, Minter said Humphrey and Vorhees avoided long-term injuries.
“They’re dealing with some small things and it may limit them for a day or two, but we feel pretty good about the rest of the guys,” Minter said.
Hendrickson, who had a finger procedure last week and missed the Titans game, was working out on an adjacent field at the start of practice.
Safety Kyle Hamilton (groin), guard John Simpson (groin) and wide receivers Zay Flowers (foot), Rashod Bateman (shoulder) and Chris Moore (ankle) were limited.
