Lamar Jackson, the Ravens’ most important player and the only one who is not practicing on Monday after the team’s break.

Jackson has been sidelined with a hamstring problem that prevented him from playing in the Ravens’ last two losses.

Jackson still has time to prepare for Sunday’s match against the Chicago Bears. After the bye week, Monday is an extra practice. Wednesday will be a crucial day for Jackson’s return.

John Harbaugh, the head coach of the Bears who won their fourth straight game last week, said he is “very hopeful’ that Jackson will be back in action against them.

Roquan Smith, the Ravens’ defensive leader and linebacker (hamstring), is back in action after missing two games.

Fullback Patrick Ricard and wide receiver Devontez Walker are also present on the field.
