Five weeks in, the Ravens have an impressively healthy roster.

All 52 players on the active roster have been practicing, and their injured reserve list doesn’t feature many key players.

However, one of the biggest contributors who is on injured reserve has experienced a setback.

Cornerback Arthur Maulet, who had a good camp and was an important part of the defensive back rotation last season, spent the first part of the season on injured reserve after undergoing arthroscopic knee surgery in training camp.

He returned to practice Wednesday, starting his 21-day practice window, and played hard during the open viewing session. Maulet then missed Thursday’s and Friday’s practices.

“He had a soft-tissue setback,” Ravens coach John Harbaugh said. “So he won’t make it to this game this week, but he’ll be day to day, probably, going forward next week. We’ll just have to see.”

Harbaugh said Wednesday that, even when Maulet is on the sideline, he makes his presence felt.

“He was flying around; he knew all the calls; he was coaching guys up,” Harbaugh said Wednesday. “He was looking forward to coming back.”

Maulet had 37 tackles, two sacks and an interception in 14 games last season. He was practicing with the starters at nickel during training camp.

Unlike Maulet, rookie running back Rasheen Ali (neck) has participated in back-to-back practices. The fifth-round pick had his first practice Thursday and was out there again Friday. To this point, the Ravens have been using only two running backs, Derrick Henry and Justice Hill, and have been successful. Ali is listed as questionable for Sunday.

Left guard Andrew Vorhees also practiced again after missing Week 4 against the Buffalo Bills. Although he was a full participant Friday, his game status is questionable.

Wide receiver and returner Deonte Harty has been a participant all week, but he was listed on the injury report Friday as questionable because of an ankle injury.

For the Cincinnati Bengals, defensive end Trey Hendrickson (neck/back), defensive tackle B.J. Hill (hamstring) and linebacker Germaine Pratt (ankle) went from limited to full participants at practice.

However, cornerback Mike Hilton (knee) is questionable, as are the two players who were designated to return, defensive tackle McKinnley Jackson (knee) and defensive end Myles Murphy (knee). Defensive tackle Sheldon Rankins (hamstring) did not practice and is doubtful.
