The Buffalo Sabres have traded forward Thomas Vanek.
Vanek has four goals and five assists in 13 games for the Sabres this season. He is Austrian and was drafted by the Buffalo Sabres fifth overall in the 2003 NHL Entry Draft - he's the highest draft pick in Austrian history.
Moulson, also 29, was signed as an unrestricted free agent by the Islanders in 2009. He's had three straight seasons of 30 or more goals for New York.
Vanek's best season was in 2006–07 when he played in all 82 regular season games for the Sabres en route to scoring 43 goals with 41 assists.
Both players are set to become unrestricted free agents next July.
