Harris, 35, is expected to miss four-to-six weeks with a torn pectoral muscle. Harris had three carries for 19 yards before leaving Toronto’s 34-27 loss to the Hamilton Tiger-Cats last weekend in the first half.
Argos head coach Ryan Dinwiddie wouldn’t discount Harris requiring season-ending surgery, either, although that determination hasn’t been made yet.
Harris, in his first season with Toronto, has rushed for 490 yards on 114 carries (4.3-yard average) while adding 23 receptions for 180 yards.
Phillips was scratched prior to last weekend’s game after suffering a groin injury during the warmup. He’s now expected to be out three-to-four weeks.
