Faulk was injured in the third period of Sunday's game against the New Jersey Devils and received an MRI on Monday. Peters ruled the Canes' All-Star defenseman out for the remainder of the week but didn't have a further update.
"I'm sure by the time we get home, the MRI results will be read and we'll know a lot more," Peters said.
Faulk, 24, leads Canes defensemen in goals (3) and ranks tied for fourth on the team in points (6). He regularly logs 24 minutes a night and skated in a season-high 27:40 in Ottawa on Nov. 1.
