Jonathan Toews wasn't fully recovered from a concussion when he played during last season's playoffs.

The Blackhawks captain wasn't 100 percent healed in July. Or October. In fact, it wasn't until late last week that Toews was convinced he's completely over the concussion that caused him to miss the final two months of the 2011-12 regular season before he returned in the postseason against the Coyotes.

While Toews was symptom-free and had cleared all the NHL-imposed concussion protocols before returning to the Hawks' lineup, there were lingering effects from the injury that even the 24-year-old center didn't realize were affecting him. They included balance and eyesight issues that were discovered and solved during a five-day stint at an Atlanta-area chiropractic neurology facility last week.
