Noting that he immediately knew something was wrong, Bulls point guard Derrick Rose confirmed Friday that theres a pretty good chance he just tore his ACL by casually glancing at his knee. I was sitting down on the couch and absentmindedly looked down for a split second, and thats when I heard a loud pop and was suddenly in excruciating pain, said Rose, adding that he felt the ligament snap the moment his knee came into his line of sight. I wasnt even really looking at the knee, per semy eyes just sort of passed over it, and then I felt it go. I should probably get an MRI just to be sure, but its already swelled to twice its normal size, so Im pretty positive I tore it. At press time, Rose had also reportedly torn his PCL and MCL after thinking the word knee.
