Manager Joe Girardi said prior to Sunday's game against the Rangers that A.J. Burnett would be on the mound for the start of a two-game series against Toronto on Tuesday and would be followed by Colon, who's filling the rotation spot of Phil Hughes (right shoulder inflammation).
Each will be going on five days' rest.
The Yankees have an off-day on Monday before traveling to Toronto, then another one Thursday before they head to Baltimore to face manager Buck Showalter's Orioles. Girardi is still unsure how he'll slot his rotation for that weekend series.
Burnett is 3-0 with a 4.67 ERA in his first three starts of the season. Colon has given up five earned runs in 11 1/3 innings out of the bullpen (a 3.97 ERA).
