Triple-A Iowa placed Canario on its 7-day injured list Friday with a right hamstring strain, Maddie Lee of the Chicago Sun-Times reports.
Iowa deactivated Canario just over a week after he was carted off the field with the injury July 24 against Indianapolis. The 24-year-old outfielder is without a clear timeline to return to action. Canario retains a spot on the Cubs' 40-man roster but had been with Iowa since July 19 following a brief stint with the big club. He maintains a .243/.336/.514 slash line over 283 plate appearances at the Triple-A level for the season.
