McLellan left Sunday's game against the Minnesota Wild after taking a stick to the head early in the second period. Wild defenseman Marco Scandella's stick hit the head of McLellan following a check.
San Jose executive vice president and general manager Doug Wilson on Tuesday released the following statement:
"Todd continues to make progress in his recovery from the stick incident in Minnesota on Sunday evening, but is still experiencing concussion-like symptoms. Thus, he will not be behind the bench until cleared by doctors to resume his coaching duties, beginning with tonight's game against the Philadelphia Flyers. While Todd will continue to provide his input on the team, we have full confidence in the abilities of assistant coaches Matt Shaw and Jay Woodcroft to lead the team in Todd's absence.
"Our main concern at this point is for Todd's full and complete recovery."
The Sharks start a four-game homestand on Tuesday.
