The Blackhawks' fourth line just isn't what is was last year when Ben Eager, Adam Burish and Colin Fraser formed one of the best in the NHL. Andrew Ebbett, claimed on waivers from Anaheim, went through his first practice with the Hawks on Tuesday and will be joining Fraser and Tomas Kopecky on the fourth line for Wednesday's home game against Vancouver. That ends the unusual shuttling of Jack Skille back and forth from Rockford on an almost daily basis. Burish won't be back until March, when he completes his rehab from knee surgery. There's no return date set for Eager, who is trying to shake off concussion-like symptoms.
