Baltimore Ravens quarterback Lamar Jackson is facing a stint on the sidelines in the run to the NFL playoffs after suffering a right ankle sprain in Sunday's 24-22 loss to the Cleveland Browns.

Jackson was doubtful pre-game with an ankle sprain and managed only four of four passes for 17 yards before taking a hit and making way for Tyler Huntley.

The former MVP left Baltimore's locker room in a protective boot.

Baltimore lead the AFC North with an 8-5 record, narrowly ahead of the Cincinnati Bengals (7-6) and Browns (7-6) with four regular season games remaining.

"Lamar has an ankle sprain. We'll look at it more [Monday] and we'll see where we're at," Ravens head coach John Harbaugh said at the post-game news conference.

"We'll see how he responds [Monday], we'll see how it responds."

Jackson is enjoying a strong season for the Ravens, completing 242 of 378 passes for 2,865 yards with a 64 percent completion rate for 16 touchdowns.

He also allowed 13 interceptions, having only committed 18 across his previous three seasons.

In Jackson's absence, backup Huntley almost pulled off a comeback victory for the Ravens against the Browns, offering hope they can still fire without their star quarterback.

"Tyler showed a lot of grit, and I felt like the whole team did that," Harbaugh said. "That's who we are and that's why we have a chance to still win the championship in the AFC North and go on from there. That's what we'll be fighting to do in the next four weeks."
