While in Florida, the Olympic swimmer was bombarded by a teen fan. The girl ran at him and although Lochte caught her, the two toppled over and Lochte hit his knee on the curb.
"As a result of a freak injury caused by an unexpected fan encounter, Ryan has suffered a torn MCL and an ACL sprain and will be taking a break from training and competition," his publicist said in a statement. "His medical team expects him to make a full and speedy recovery and Ryan thanks everyone for their well wishes."
Lochte, 29, won two gold medals, two silver and a bronze at the 2012 London Olympics.
