Salak, 24, was acquired on Feb. 9, 2011 in a trade with the Florida Panthers. He played for Farjestad BK in the Swedish Elite League in 2010-11. He ranked second in the league with a 1.97 goals against average and a .926 save percentage.
Sources familiar with the deal say Salak's contract is for $1.2 million or $600,000 per year. Salak's deal is a one-way contract, according to the source, meaning he's paid the same if he plays in the AHL or NHL.
The Blackhawks also signed forwards Byron Froese and David Gilbert to three-year, entry-level deals. Froese was a fourth-round pick of the team in 2009 while Gilbert was drafted in the seventh round the same year.
Froese scored 43 goals playing for Red Deer in the Western Hockey League. Gilbert had 28 goals and 51 points playing in juniors this past season before joining the Rockford (AHL) IceHogs for five games, amassing two goals and an assist.
