The contract is worth $29.7 million, according to ESPN's Pierre LeBrun.
Bobrovsky, 26, is currently in his third season with Columbus. He was acquired in a trade from the Philadelphia Flyers for second-, third- and fourth-round draft picks. In his first season with the Blue Jackets, the lockout-shortened 2012-13 season, he won the Vezina Trophy as the league's top goaltender.
"A common thread of every successful team in our league is outstanding goaltending and we believe we have one of the best at the position in the world in Sergei Bobrovsky,” Blue Jackets GM Jarmo Kekalainen said in a statement. "He is a tremendous person and a very talented player whose work ethic sets the tone for our team. We are very happy to have him signed for the next four years."
This season, Bobrovsky is 15-10-2 with a .917 save percentage and a 2.75 goals-against average.
