Garon was originally signed by the Oilers prior to the 2007-08 season. In 15 games this year, he went 6-8-0 with a 3.17 GAA and a save percentage of .895.
Sabourin has similar statistics this season in Pittsburgh. He played 18 games and had a record of 6-8-2, with a 2.85 GAA and a save percentage of .898.
"Addressing our goaltending situation was a high priority for us and moving forward, we believe we've accomplished that as well as acquiring some valuable assets for our organization," Oilers general manager Steve Tambellini said in a statement to the Canadian Press.
"I don't plan on bringing him [Sabourin] to Edmonton; either through trade or placement in Springfield, we'll see what happens the next couple days," Tambellini told radio station CHED 630 in Edmonton.
Stone has spent most of the season in the AHL with Scranton Wilkes-Barre. He has zero points in 2 appearances with Pittsburgh.
