At last Thursday’s Quintet Ultra event, in the semi final between team UFC and team WEC (See full results here), Jake Shields defeated Cub Swanson via knee injury at 5:18 mark. Shields had reaped Swanson’s knee going for a leg lock sweep which put tremendous amounts of pressure on his opponent’s knee.
Shield stated on his instagram:
Had a tough match with cub Swanson last night despite the weight differences. Unfortunately going for a sweep leg lock i felt some bad knee pops ending the match. Hopefully cub is healthy and can fight again soon…
Shields then answered a fan question about if this was caused by knee reaping:

Swanson simply tweeted the outcome and will see a doctor on Monday:
Well it looks like a full ACL & Meniscus tear. I see the specialist on Monday pic.twitter.com/FbTsT1kURH

Well he did see a doctor this Monday morning and the outcome was as expected.
Swanson stated on his instagram:
I had a great time at the event last night. Unfortunately I suffered a complete ACL & Meniscus tear from this reap 🤦🏽♂️

What does this mean for Cub Swanson’s UFC career? After his victory over Kron Gracie, Swanson was back on the right track. At age 36, he may need significant time in order to recover from such a serious injury.
Average recovery time after a torn ACL & meniscus injury is typically around six to nine months in order to return to normal activity. Without a normal ACL, the knee becomes unstable and can buckle, especially when the leg is planted and attempts are made to stop or turn quickly.
So how dangerous is knee reaping?
Knee reaping is illegal in IBJJF tournaments and tournaments that run under the IBJJF rules.
