Several Ravens starters sat during Tuesday's practice

Like the every franchise in the National Football League, the Baltimore Ravens practiced on Tuesday as they prepare for a must-win game against Bengals in Cincinnati. Baltimore needs a win and a loss by the San Diego Chargers or Miami Dolphins to qualify for their sixth straight postseason appearance. There is one scenario in which Baltimore can make it without needing a win, but require losses by the Miami Dolphins, San Diego Chargers and Pittsburgh Steelers -- any one of those teams win with a Ravens loss, eliminates Baltimore.

As they worked indoors in preparation for Sunday's game, several Ravens starters sat.

Defensive lineman Arthur Jones suffered a concussion on Sunday against the New England Patriots and, according to Aaron Wilson with the Baltimore Sun, is still undergoing concussion protocols. Jones has started 13 games this season, generating a career-high 53 tackles and 4.0 quarterback sacks. He's the second-best Ravens defender (to Elvis Dumervil), according to Pro Football Focus and the second-best run defender.

Wide receiver Torrey Smith, "appeared to injure his hamstring" against the Patriots but Wilson suggests that "the injury isn't considered serious." Smith has generated a career-high 1,101 yards receiving this season and needs 101 yards to surpass Michael Jackson's single-season record (1,201 yards in 1996) for yards receiving in a season.

Ray Rice isn't concerned about a quadriceps injury that he's been dealing with since Detroit, calling Tuesday a rest day. Outside linebacker Elvis Dumervil sat during 11-on-11 work (team drills) with a sprained ankle.

Like the Bengals, Baltimore had a lengthy injury report but that's mostly related to the fact that teams are practicing two days after their most recent game. Usually players rest on Tuesday and practice on Wednesday, but Christmas landing on a Wednesday changed that routine.
