The 38-year-old is currently listed as day to day, but the hope remains that Dickey will make his next scheduled start on Tuesday against the Orioles.
"He's feeling a little better today," manager John Gibbons said. "[Saturday] is his side day, we'll get a little better idea."
Dickey first began experiencing the symptoms during his last start against the Royals. The discomfort carried over into his next outing, and he was seen grabbing the affected area multiple times throughout the start.
The discomfort might have been there, but it certainly didn't affect his performance on the mound. Dickey had his best start to date in a Blue Jays' uniform by allowing just two hits while striking out seven in his six scoreless innings.
