Overview

• General manager Jim Nill announced the diagnosis and planned surgery after the issue was identified in the third period Tuesday versus the Wild.
• Dallas will reassess Benn in four weeks, which makes an opening-night absence likely and points to missing at least the early portion of the schedule.
• Benn played 15:47 in the 3-2 overtime win over Minnesota and had been lining up with Matt Duchene and Tyler Seguin during preseason.
• The update replaces Wednesday’s description from coach Glen Gulutzan that listed Benn as day-to-day with an upper-body injury.
• The longtime captain returned on a one-year, $1 million deal with up to $3 million in bonuses, creating short-term lineup and leadership adjustments for a team with Cup aspirations.
