Sharks' Tommy Wingels: Leaves with mystery ailment Friday

Wingels was forced out of Friday's game against the Islanders in the first period due to an undisclosed injury, the San Jose Mercury News reports.

Analysis:

The Sharks were quick to rule out a concussion for Wingels, but to suspect such a specific injury in the first place suggests that he's dealing with some type of upper-body issue. With San Jose entertaining the Ducks on Saturday, the team won't have much time to give him a thorough evaluation ahead of that contest. He's day-to-day until further notice.
