Brown is expected to be sidelined for 4-6 weeks with an upper-body injury, TSN 1200 Ottawa reports.
Brown's extended absence will test the Senators' depth at defense, but it won't impact many fantasy lineups, as he's gone scoreless while posting a minus-5 rating through 12 games this campaign. The 27-year-old blueliner may have to wait for the calendar to flip to 2022 before getting the green light to return to action.
