Nash, who has 13 goals and 20 points in 30 games this season, missed four games from Dec. 8-13 with a groin injury. He returned for the next three and even scored two goals, including a game-winner against the Dallas Stars in his first game back on Dec. 15.
However, Nash admitted he was feeling lingering pain in his groin during those three games. That forced him out of the lineup again, and he hasn't played since Dec. 18.
"That's my own fault," Nash said. "The trainers told me they wanted me to feel better, but being an athlete, being a competitor you feel you can play through it. I probably should have done a better job listening."
Nash said he doesn't feel any lingering pain when he skates now, but he expects it will take him a few games to feel like he did before he initially sustained the injury, when he felt like he was skating well, getting to the net, getting chances and playing a strong two-way game.
"Realistically I think it'll take a few games to feel confidence in the groins again," Nash said. "I think it'll take a few games to find my lungs. Even though we've been going hard on the bike and hard on the ice, there's nothing like playing a game."
