Lamar Jackson did not return to Week 13 game after appearing to suffer a left knee PCL sprain on a sack at the end of the first quarter against the Broncos.Based on video of the injury, Jackson is unlikely to play for at least the next two weeks, according to the Pro Football Docs. That knocks him out for next week against the Steelers and Week 15 against the Browns.#Ravens QB Lamar Jackson is questionable to return with a left knee injury he suffered on this sackFull analysis: https://t.co/hSc4nfeXyI pic.twitter.com/rpMhJ1U8iB— Sports Injury Central (@SICscore) December 4, 2022 He could return for Week 16 against the Falcons, but he might not be 100% by then.Head coach John Harbaugh told reporters after the game, “Certainly by Wednesday, it will be more definitive, but it's going to be a number of days to weeks.”Cowboys running back Ezekiel Elliott suffered a PCL sprain in Week 9 last season and did not miss any game time, but he admitted that he was not 100% the rest of the season.The Ravens are unlikely to risk playing Jackson at less than 100%, especially with a capable backup in Tyler Huntley.Huntley took over at quarterback against the Broncos and has experience starting in place of Jackson.The third-year quarterback finished 27 of 32 for 187 yards and an interception, plus 10 carries for 41 yards after replacing Jackson in the second quarter.He averaged 193 passing yards and 59.75 rushing yards in four starts for Jackson last season.
