When Jared Gaither left Friday afternoon's practice on a cart, the team said that the offensive tackle was experiencing cramps.
Gaither hasn't practiced since, however, and the Ravens are now uncertain of what exactly is wrong with the fourth-year pro.
"I'd like to be able to tell you what it is," head coach John Harbaugh said. "I don't know. He's getting blood work, and they say they're going to do some tests on him on Monday, and they'll tell us what it is. That's all they've told me, they really don't know."
Gaither reported to camp seemingly in good shape and good spirits, although he looked significantly slimmer than in previous seasons. He said on Friday that he had lost 25 pounds, and Harbaugh said Gaither now weighs 311 pounds, something which apparently isn't sitting well with the coaches.
"He made a decision," a clearly bothered Harbaugh said. "He was working out on his own, so it's not like he was around. He made the decision to go a little lighter. I can't even explain to you why."
Gaither missed almost all of the team's OTAs with a foot injury, but seemed to be around his 2009 playing weight of 340 pounds at the beginning of minicamps. The team wasn't able to monitor his conditioning between OTAs and training camp, and it appears that Gaither's plan to shed some pounds caught the Ravens off guard.
Here was Gaither's rationale for the weight loss when I talked to him on Friday:
"I was trying to take some weight off the toe to make sure everything's OK, less stress, and I did pretty good with it," Gaither said. "I feel great, and it was good for me."
It's obviously unclear at this point if Gaither's health issues are related to the dramatic weight loss.
