Problems with this news:
1. KZ is going to get annihilated. He's a very good [and exciting] fighter, but Aldo is better everywhere.
2. I doubt we ever see Pettis/Aldo. Mayne, this fight was the definition of a toss-up, we could've seen Aldo get rocked for the first time. Pettis will likely heal up and fight for the LW title. By far, the most exciting fight/match-up, gone..
3. We don't get to see Lamas/KZ.
4. I heard that it's a torn meniscus, so I doubt we see Pettis fight this year.
On the bright side, this fight will be exciting while it lasts.
Edit: Just read that it's a small tear, so the recovery time is expected to be 4-6 weeks [if all goes to plan]
