He's expected to be a game-time decision on Sunday, according to coach John Harbaugh, who didn't rule out the possibility of Dumervil playing after not practicing all week.
"Earlier in the week, we felt like he was going to make it," Harbaugh said. "He's not a guy who has to practice to play. So, if he goes out there and feels like he can go, he will."
Dumervil returned to finish the game against the Steelers after hurting his ankle and hasn't been limping noticeably in the locker room this week.
Dumervil leads the Ravens with 9.5 sacks and has also forced two fumbles.
Dumervil's status for Sunday against the Minnesota Vikings hasn't been determined. Typically, players who miss all three practices are held out on Sunday under coach John Harbaugh. However, Dumervil could be an exception if his ankle responds well in the next few days and he's able to test it out during warmups on Sunday at M&T Bank Stadium.
He hasn't missed a game since the 2011 season with the Denver Broncos.
Meanwhile, rookie safety Brynden Trawick remains sidelined with a high-ankle sprain that's kept him out for two games and two weeks of practice. He's a candidate for injured reserve once the Ravens activate tight end Dennis Pitta as soon as Saturday afternoon from injured reserve-designated to return list.
Pitta is expected to be activated this week and play Sunday on a limited basis as he continues to make progress with his surgically repaired right hip, according to sources.
Pitta has practiced since Nov. 20, increasing his workload to include team drills after being limited to individual drills the previous two weeks.
Reserve cornerback Asa Jackson returned to practice from a thigh injury.
