Braves pitcher Matt Marksberry was being treated for severe dehydration in an Orlando-area hospital Wednesday after going in for a procedure unrelated to baseball. A Facebook post from his brother Wednesday afternoon said that Marksberry was on life support. Others familiar with the situation said Wednesday night that the pitcher was unconscious, apparently in a medically induced coma, but that his vital signs were good. A Braves spokesman said only that Marksberry was being treated for “severe dehydration” and that HIPAA rules prohibited the team from divulging any further information. The rules are particularly restrictive since Marksberry’s health situation was not baseball-related. Marksberry, 26, said on his Twitter page Monday: “I don’t want to sound selfish but I really could use some prayers for my health right now. Non baseball related. Thank you guys.”
