Arizona Cardinals rookie Tyrann Mathieu's Monday morning MRI revealed he suffered two torn ligaments in his left knee.
The safety tore both the anterior cruciate and lateral collateral ligaments in his knee after being injured while returning a kick in the third quarter against the St. Louis Rams on Sunday.
Mathieu, according to a source, will probably wait a week to 10 days to have surgery so the LCL heals and the fluid can drain out of it.
The rehabilitation is expected to be longer than just a typical ACL rehab. He's looking at two months before he can put any weight on the knee. But Mathieu plans to be ready for the season opener.
"He's been bawling since he's got the news," cornerback Jerraud Powers said Sunday. "It's going to be a huge blow. I just feel bad for him. Guys like him and Patrick (Peterson), football is the world and more to them. (Mathieu) really feels blessed just to be on the field."
Outside linebacker John Abraham said the Cardinals will miss Mathieu's passion.
"My thing is it's more about his personality, his urge and his mentality on the field," Abraham said. "Even though he's a young guy, he prepares like a vet and he acts like a vet. I think that's one of the biggest things we're going to lose."
Mathieu, who earned the nickname "Honey Badger" in his days at LSU, was Arizona's starting safety and had been in on almost every defensive play for the Cardinals.
