Spezza revealed the nature of his injury after the team's morning skate at Canadian Tire Centre. He said he sustained the injury Saturday during Ottawa's 4-3 win against the Boston Bruins.
"I just kind of lost my balance at the start of the second period on the boards and as I was falling I kind of pulled something," Spezza said. "I finished the game and felt all right and thought I'd be fine the next day. Then I woke up and I was sore."
Spezza didn't have a timeline for his return but said he feels like he is making progress and doesn't expect it to be a long-term injury.
"We want to make sure that I squash it so that it's like anything, groins, hips, you don't want them to linger," Spezza said.
