Symptoms from collision remain for Hamilton

Symptoms from collision remain for Hamilton

CINCINNATI -- The chances of Reds rookie outfielder Billy Hamilton returning during the final series of 2014 seemed diminished on Friday. Hamilton is still feeling the effects of a mild concussion suffered on Wednesday, as well as neck and shoulder soreness.

Hamilton, who was injured during a wall collision while taking a home run away from the Brewers' Ryan Braun, has not undergone the concussion testing protocol required by Major League Baseball before he can be cleared to return.

Reds head trainer Paul Lessard said Hamilton still felt symptoms when he attempted to use an exercise bike in the training room.

"Although he was asymptomatic when he came in, unfortunately after the bike ride, he became more symptomatic," Lessard said. "I can't progress him until those symptoms are gone. With the way that went, there is no sense doing a computerized test, because I know he won't do well with it.

"It's basically a day-to-day thing. When he is asymptomatic with some light exercise, then we might do the other testing."
