Update: Lehtonen (back) has officially been sent to Dallas in exchange for defenseman Ivan Vishnevskiy(notes) and a fourth-round draft pick, Chris Vivlamore of the Atlanta Journal-Constitution reports.
Recommendation: Since the Thrashers haven’t had any production from Lehtonen all season long, they’re essentially getting Vishnevskiy for free. Atlanta now only has four players remaining from the 2006-07 team, which is the only playoff team in franchise history.
