Minnesota's Percy Harvin said his heated dispute with Brad Childress last Friday was over an MRI the wide receiver didn't want to take but that he and the coach are "fine" now. "We had a little dispute," Harvin told The Star Tribune. "It wasn't what people thought it was about. It was about whether I was going to get an MRI or not. It was a little dispute, but we settled it. Me and Coach are fine." Childress questioned Harvin's effort during the practice, sources told ESPN.com's Ed Werder. When Harvin took exception, Childress suggested Harvin submit to further testing on the ankle. The debate escalated and "was as close to physical as you can get," according to a source.
