Vanecek was acquired by the Panthers from the Sharks on Wednesday in exchange for Patrick Giles, George Richards of Florida Hockey Now reports.
Vanecek is currently mired in a seven-game losing streak, having gone 0-5-2 with a 4.46 GAA over that stretch. Overall, the 29-year-old Czech has managed a meager three wins in his 18 appearances for San Jose this year. With the move to Florida, Vanecek figures to slide into the No. 2 role behind Sergei Bobrovsky.
