Toews was slashed by defenseman Erik Gudbranson on Friday night against the Florida Panthers favoring his left hand for a portion of the game, but stated that he was fine after the contest.
It is unclear if Toews aggravated this injury or suffered a new one.
"We'll know more over the next day or so. We'll say day to day," coach Joel Quenneville told the Tribune.
In 49 games with the Hawks this season, Toews has collected 27 goals and 23 assists for 50 points.
