Witt, 34, was activated off injured reserve this week after sitting out most of last month with a knee injury.
Witt has two goals and five points in 42 games this season. If he clears waivers after 24 hours, the club will likely send him to their American Hockey League affiliate in Bridgeport.
With all this talk about the Hawks needing a physical, veteran blueliner Witt is the ultimate deal. If they pick him up off waivers the Hawks will split $3.0 million dollar salary with the Islanders for the rest of the season, with the added bonus that he is a UFA and the end of the year. Much better than wasting Buff or Versteeg on someone like Jay McKee.
