Hudson, Boyer injured in same inning

Starter strains left hamstring; reliever's right knee is sore

CINCINNATI -- If Braves manager Bobby Cox only had to assess yet another miserable road trip at Great American Ball Park on Sunday afternoon, he'd have had the right to be in a horrible mood.

Throw in the fact that he also had to answer questions about the injuries Tim Hudson and Blaine Boyer suffered in the seventh inning of Sunday's 6-2 loss to the Reds, and it's understandable why he didn't feel like saying much at all.

The early diagnosis is that Hudson suffered a left hamstring strain and Boyer has a sore right knee. Both pitchers will be evaluated by the Braves' medical staff in Atlanta on Monday.

"I didn't feel any pop like you usually do when you blow it out," Hudson said. "But I definitely felt a little zing in there."

Hudson felt some discomfort while throwing a warmup pitch before the bottom of the seventh inning. The pain worsened after he threw his first pitch of the inning. Based on the pain he was feeling after the game and his experience with other hamstring ailments, the Braves' ace believes he'll be able to make his scheduled start on Friday against the Phillies.

"I don't think it's anything that's going to make me miss any starts," Hudson said. "I had a pulled hamstring a few years back, and it was a lot worse than this, and I kind of pitched through it. It's just something you've got to deal with in between starts."

After tending to Hudson, Cox's stay in the dugout wasn't long. He was forced to come back to the mound just 13 pitches later to remove Blaine Boyer, whose knee buckled while he was throwing a pitch to Brandon Phillips. He had made the same sort of awkward delivery two batters earlier on a pitch to Jay Bruce.

Doctors told Boyer that his knee appeared to be structurally sound. After the game, he was able to simulate a portion of his delivery without any apparent discomfort. An MRI will be performed on Monday to provide more answers for the right-handed reliever, who has made a team-high 31 appearances this year.

"They think I might have strained something," Boyer said. "We'll be able to find out more [on Monday]. I don't think it's serious."
