UFC middleweight champion Chris Weidman went under the knife yesterday to fix a lingering knee injury which had been affecting him during training and also forced him to drop out of his main event spot with Lyoto Machida at UFC 173.

Fortunately for the "All-American" the surgery was a complete success and the 29-year old is expected to make a complete recovery. If all goes according to plan, Weidman should be back to full training in around five weeks time.

The middleweight champ posted an update on his Instagam to let his fans and followers know he was ok. Weidman uploaded a photo onto his account following his surgery and posted a message thanking people for their support:

“Surgery was a success!” Weidman wrote on Instagram. “Thanks for all of the prayers and well wishes"

Weidman was expected to try and defend his world title against "The Dragon" on May 24, but had to pull out when he damaged his knee in training. In his place the UFC booked a bantamweight title fight between current champ Renan Barão and Team Alpha Male standout; T.J. Dillashaw.

Officials then postponed the middleweight title fight between Weidman and Machida until UFC 175 on July 5, giving the undefeated champ time to get the minor surgery on his injured knee.

UFC 175 is set to go down inside the Mandalay Bay Events Center in Las Vegas Nevada. So far only two other matchup's have been announced for the event: Dan Henderson vs. Daniel Cormier and Uriah Hall vs. Thiago Santos.

The event comes during International Fight Week for the UFC, where the promotion has set itself a busy schedule. Just a week before UFC 175, UFN 43: Swanson vs. Stevens will take place.

Then on July 6, the day after UFC 173, the promotion will host The Ultimate Figher 19 Finale. TUF 19 Finale is headlined by a featherweight trilogy between former lightweight champions B.J. Penn and Frankie Edgar.
