Things have gone from bad to worse on the Blue Jays pitching front.

Having lost starter Brandon Morrow on Monday due to a left oblique strain, on Wednesday the Jays also ran into problems with Kyle Drabek.

In the fifth inning of a 6-2 loss against the Washington Nationals, Drabek, with one out, threw a fastball to Michael Morse and instantly knew that something was wrong.

"I threw the ball and I kind of felt a popping sensation in the back of my elbow," the right-hander said. "I don't know how fast it was but I knew the velocity was down and just for precautions, it was probably smart to take me out."

The good news, if there was any this day, is that initial testing didn't reveal any major damage. Drabek, who had Tommy John elbow ligament transplant surgery in 2007, said he didn't believe that there was a recurrence of that problem this time around.
