"I don't know if it's going to be long term," he said referring to the injury. "He's day-to-day. He's here every morning getting his rehab and actually went on the ice there a little bit. We'll know a little bit more as each day goes by."
Capuano characterized Grabovski's skate on Tuesday morning as a "light skate, but it's a good sign that he's progressing." Grabovski left last Thursday's game against the San Jose Sharks after being hit hard by John Scott. He originally passed a concussion test, but woke up on Friday with concussion like symptoms.
Seeing Grabovski back on the ice is a good sign -- as Capuano had said -- although it still could take some time for him to make it back to the line-up. As a result of the injury Colin McDoanld made his 2014-15 debut on Saturday in the Islanders 3-1 loss to the Pittsburgh Penguins.
Grabovski will miss the Islanders first game against the Toronto Maples. He spent five years with the Leafs before signing with the Washington Capitals during free agency in 2013.
The 30-year-old had two goals and an assist for three points to start the season with the Islanders prior to the injury.
