EAGAN, Minn. -- How does an NFL player suffer a season-ending injury without knowing it? Minnesota Vikings quarterback J.J. McCarthy explained that circumstance and much more Friday in his first interview since undergoing surgery to repair a radial tear of the meniscus in his right knee.
McCarthy told a group of local reporters that he didn't realize he was injured until the morning after his promising preseason debut Aug. 10 at U.S. Bank Stadium. His knee buckled as he walked down the stairs at his home, and by the following day the onset of soreness was significant enough to report to team medical officials.
