Our best guess on the list for Sunday's game against the Ravens:
Michael Buchanan: Rookie defensive end was a healthy scratch for the first time last Sunday, as fullback James Develin took on some of his special-teams duties. Buchanan hasn't played on defense since Nov. 3 against the Steelers.
Nate Solder: Starting left tackle has been on the injury report the past two weeks with a concussion and left last Sunday's loss to the Dolphins in the fourth quarter after getting kicked/kneed in the head. He missed Wednesday's practice and was limited on Thursday and Friday.
D.J. Williams: With Michael Hoomanawanui returning to the lineup last week, and playing a tight end-high 71 snaps, Williams as a third option at the position gets trumped by needs at other positions.
Duron Harmon: Rookie safety provides key depth, but in a week where there aren't as many players to rule out because of injury, and with him not playing on any first-string special-teams units last week, he could be edged out in favor of a fourth defensive tackle with a physical game in mind.
Steve Beauharnais: Linebacker, a seventh-round pick out of Rutgers, is on the developmental track as he's been inactive for 11 games this season.
Jake Bequette: Second-year defensive end is fifth on the depth chart and has been inactive the past seven games.
Josh Boyce: Rookie receiver and primary kickoff returner has already been ruled out with an ankle injury sustained in the fourth quarter last Sunday.
