Kukan left part of Tuesday's Game 2 after suffering a hard hit in the first period but did return, and Tortorella said after the game that the Swiss defenseman was fine. But if he weren't, the Blue Jackets have plenty of depth in reserve, including Nutivaara, who has been a standout playoffs performer in the past; Harrington, who was a full-time player a year ago and is a six-year NHL veteran; Peeke, a rookie who showed excellent promise this year; Clendening, who stepped into postseason play last year; and Carlsson, who essentially debuted with postseason hockey as a rookie.
