Edge rusher Marcus Davenport will miss at least four games after the Vikings placed him on injured reserve Wednesday. The team will reevaluate Davenport after four weeks, defensive coordinator Brian Flores said.
Davenport suffered a high ankle sprain while appearing to collide with defensive tackle Harrison Phillips, who sacked Bears quarterback Justin Fields on the play. Davenport was carted to the locker room and seen in a walking boot Sunday after the Vikings' 19-13 win in Chicago. The earliest Davenport can return is Nov. 19 against the Broncos.
"Losing Marcus is a big loss," Flores said, "but we'll need to just collectively pick up the slack in all areas."
The Vikings signed Davenport, a former Saints first-round pick, to a one-year deal worth up to $13 million in March. A right ankle injury suffered days before the Sept. 10 season opener kept him sidelined for all but four snaps of Weeks 1-3. He has two sacks in four appearances — two limited by injury — this season.
The Vikings' available edge rushers include Danielle Hunter, D.J. Wonnum, Patrick Jones II and rookie Andre Carter II on the active roster. Edge rushers Benton Whitley and Luiji Vilain are on the practice squad.
Running back Kene Nwangwu (back) has been activated from injured reserve. He is expected to return to his role as kick returner on Monday night against the 49ers, said special teams coordinator Matt Daniels. The speedy runner has dealt with a back injury since early August.
The Vikings still have an opening on the 53-man roster after waiving receiver Trishton Jackson, who re-signed to the practice squad on Wednesday. Receiver Jalen Nailor (hamstring) could take that spot. He is expected to practice this week after being designated to return from injured reserve.
Cornerback Akayleb Evans participated in the Vikings' walk-through Wednesday (closed to reporters) and said he's feeling "a lot better" with the oblique strain that led to him missing snaps in the fourth quarter of Sunday's win at Chicago. Evans said he expects to play against the 49ers. The team's first injury report will be issued Thursday.
