Toronto Blue Jays closer Ken Giles was unavailable for Saturday's game against the New York Yankees because of nerve inflammation in his right elbow that potentially stemmed from a massage he had over the All-Star break, manager Charlie Montoyo said.
A possible trade target, Giles missed 10 days in June with a mild case of elbow inflammation, but Montoyo noted that this new case was unrelated to his previous one.
Giles is considered day-to-day and is not scheduled for tests.
"Nothing serious," Giles told reporters after Saturday's 2-1 win over the Yankees, according to the Toronto Star. "Just a little fatigue. I got some work done during the All-Star break. A little sore from it still, so we're being cautious with it. Just a little irritated. I'm day-by-day right now and hopefully I'll be back on the mound tomorrow."
Daniel Hudson closed out the Jays' win Saturday in Giles' place.
Giles has 13 saves and a 1.45 ERA in 31 appearances this season.
Giles' would not be the first massage-related injury MLB has seen this year. In May, Houston Astros shortstop Carlos Correa said he suffered a fractured rib during a massage at his home.
