Rookie quarterback Lamar Jackson was back at practice with the Baltimore Ravens on Friday after sitting out the day before because of a stomach ailment, and he might start against the Cincinnati Bengals on Sunday.
That's because starter Joe Flacco missed his third practice of the week because of a right hip injury he sustained two weeks ago against the Pittsburgh Steelers and is listed as doubtful for this week, even though he had the bye week to heal.
The Ravens (4-5) also could go with veteran Robert Griffin III, who was the only quarterback at practice on Thursday, but he has not been active for a game this season.
The 28-year-old Griffin has played 42 games in his NFL career with the Washington Redskins and Cleveland Browns, passing for 8,983 yards and 42 touchdowns with 26 interceptions.
Jackson, 2016 Heisman Trophy winner and the Ravens' first-round pick (No. 32 overall) out of Louisville, has played in every game this season at several positions. He completed 7 of 12 passes for 87 yards and a touchdown, in addition to rushing 28 times for 139 yards and another score.
Head coach John Harbaugh has not said whether Jackson or Griffin would start if Flacco can't play, but he also has said that his starter could play without practicing if he is healthy.
The Ravens ruled right tackle James Hurst (back) and linebacker Tim Williams (ankle) as out for the Bengals game.
