Baltimore Ravens defensive lineman Art Jones will visit a specialist on Wednesday to determine what sort of illness he has.

Jones' illness is not football-related, nor is it life-threatening, according to Ravens coach John Harbaugh, who did not elaborate on the matter much more than that.

"I'd rather leave an explantion of Art's situation up to Art," Harbaugh told the Baltimore Sun. "It's not anything that's like life-threatening or anything like that. It's non football related. We've got to get some tests done to make sure that he's OK. Until the tests come out the right way, he's not going to be able to play.

"It's something Iv'e been told now that they can't tell you how long it's going to be. It could be a week, it could be indefinitely. W don't think it's going to be the second part. He's going to see a specialist here on Wednesday and he can explain to you exactly what it's about, to whatever extent he wants to."
