The Toronto Blue Jays say right-handed pitcher Kyle Drabek has a torn elbow ligament and will visit renowned surgeon Dr. James Andrews on Monday to confirm the diagnosis.
Drabek was put on the 15-day disabled list earlier Friday with the team stating in a news release that he had a strained ulnar collateral ligament.
Lefty Brett Cecil subsequently was recalled from AAA Las Vegas and will start in Sunday's series finale against the visiting Philadelphia Phillies.
Drabek (4-7) was forced to leave Wednesday's game against the Washington Nationals in the fifth inning after suffering the injury.
Afterwards, he declared the elbow didn't feel as bad as it did in 2007 when Drabek had UCL replacement (Tommy John) surgery. Should Dr. Andrews confirm the latest diagnosis, the young hurler will be facing his second such procedure.
"It's nothing like ['07], but it's always frightening," said Drabek on Wednesday. "Not too concerned. Once I ran through all the tests and I was strong, it was a relief. … It's just a little sore right now, obviously I want to go back out and pitch but it's up to the trainers and coaches."
In 13 starts this season, Drabek has a 4.67 earned-run average while holding opponents to a .250 average.
Two days ago, Toronto starter Brandon Morrow was placed on the DL with a strained oblique, or rib cage muscle.
The right-hander exited Monday's game against Washington after nine pitches.
A second round of tests Tuesday confirmed the initial diagnosis, and there is no timetable for Morrow's return.
Morrow entered Monday's game having won three of his previous four starts, a stretch in which he also threw two shutouts.
Morrow has a career-high three shutouts this season to go with a 7-4 record and 3.01 ERA in 13 starts.
