A knee injury was the culprit behind Alexa Grasso’s withdrawal from UFC Fight Night 135.

Grasso (10-2 MMA, 2-2 UFC) was forced to pull out of a scheduled strawweight bout with Angela Hill (8-4 MMA, 3-4 UFC) at UFC Fight Night 135 in August for what was originally described as an “undisclosed” reason.

The 23-year-old Mexican fighter has provided some further clarity, and revealed it was an LCL tear that prevented her from moving forward with the bout. The upside, however, is that Grasso will not require surgery (via <a href="

I’m sorry to tell you that I’m out of my fight in Nebraska next August 25th.

In a training I made a wrong exit and I have a LCL break. This pain prevents me from doing many activities to improve my camp quality. Fortunately I do not need surgery, some fibers are still attached and doctors say that with therapy and physical rehabilitation I will be fine again. I can do push-ups, sit-ups, pull-ups and all of the top gear so I’ll be doing these weeks. Thank you #SportMed Dr. Fco. Arroyo, Wilson Peregrina, Carlos Villanueva and Luis Lamadrid for always taking care of my health.

I am in a contact sport and they are accidents to which any athlete is exposed. I’ll be fine in a few weeks and I’ll train again to be ready.

I thank all those little people who took time to send me good vibes, I love them very much! 😘☘

Grasso did not express the exact timeline for her recovery, other than indicating it would take a “few weeks” before she’s able to return to proper preparation. In the meantime, Grasso was replaced by Cortney Casey (7-5 MMA, 3-5 UFC) in the fight vs. Hill at UFC Fight Night 137, which takes place Aug. 25 in Lincoln, Neb.
