Ravens' Lamar Jackson: May not play again until Week 16

Jackson (knee), who is listed as doubtful for Sunday's game at Pittsburgh, may not be cleared to play until the Ravens' Week 16 game against the Falcons on Dec. 24, Adam Schefter of ESPN reports.

Jackson is tending to a sprained PCL in his left knee, an injury he sustained in last week's win over the Broncos. The quarterback was given an estimated recovery timeline of 1-to-3 weeks, so Schefter's report would seem to suggest the signal-caller is trending toward the back end of that range. After failing to practice this week, Jackson will most likely be inactive for Sunday's contest, after Baltimore called up Anthony Brown from the practice squad with the expectation that he'll serve as Tyler Huntley's backup in Pittsburgh. The Ravens will wait and see what kind of progress, if any, Jackson makes over the next several days before a decision is reached on his status for the team's Week 15 game at Cleveland, which will be played next Saturday.
