The White Sox recalled Cannon from Triple-A Charlotte on Tuesday, LaMond Pope of the Chicago Tribune reports.
With Huascar Brazoban (lat) headed to the IL, Cannon will come up from Triple-A to replenish Chicago's bullpen depth. The 26-year-old has allowed 14 runs (13 earned) in 16 innings across his last three minor-league outings, and he walked three batters and gave up a run without recording an out during his lone MLB appearance this season.
