According to the San Jose Mercury News, Sharks General Manager Doug Wilson said McLellan was conducting practice as part of the post-concussion protocol. The medical team then would provide further tests, and only then will his availability be determined.
McLellan has missed the past two games. He was hit by a stick in Sunday's 4-3 loss to the Minnesota Wild, and has been suffering from concussion-like symptoms. In his absence, assistant coach Jay Woodcroft has been running the bench.
