Baltimore Ravens quarterback Lamar Jackson returned to practice on Wednesday but remains in doubt for Sunday's must-win game against the Los Angeles Rams.

Jackson has been battling a right ankle injury over the past fortnight having missed their past two games and practiced with a visible limp on Wednesday.

Ravens head coach John Harbaugh indicated it is expected the 24-year-old QB will have limited preparation ahead of Sunday's game.

"I'm really hopeful," Harbaugh told reporters. "I'm hopeful for all our quarterbacks, starting with Lamar.

"I really want to see him out there on Sunday. I know the fans do, and I know most of all, Lamar does.

"He's going to do everything he can to be out there. You can't make a promise because we don't know what tomorrow is going to bring."

Jackson has not played since sustained the injury in the 24-22 loss to the Cleveland Browns on December 12.

The Ravens have lost their past two games without Jackson, stretching their losing run to four games and leaving them with an 8-7 record and in danger of missing the playoffs.

Tyler Huntley will stand in for Jackson if he is not deemed fit, given he is expected to be activated off the reserve/COVID-19 list on Thursday.

Jackson has thrown for 2,882 yards and 16 touchdowns this season along with a career-high 13 interceptions. The 24-year-old has also rushed for two scores – the lowest of his career – on 133 carries in 2021.
