The 29-year-old Olympic swimmer was injured earlier today when an overzealous female fan rushed him and knocked him to the ground.
Yeah, that's right--Ryan was essentially tackled by a teenage girl.
According to TMZ, he took the hit pretty hard, tearing his MCL and spraining his ACL in the process (the girl was not hurt in the take down).
Ryan will be out of the pool for awhile, but his publicist said in a statement that they expect the swimmer "to make a full and speedy recovery."
Get well soon, Ryan!
