Frankie Edgar slapped with a 2-month medical suspension after he was KO'd by a flying knee in just 28 seconds

• Frankie Edgar was knocked out in 28 seconds from a flying knee at a UFC event Saturday.
• The Nevada State Commission slapped him with a two-month suspension to ensure he recovers.
• The commission issued suspensions to 16 of the 24 fighters competing in Las Vegas.

Frankie Edgar has been slapped with a two-month medical suspension after he was knocked out by a flying knee after just 28 seconds on Saturday night.

A mixed martial arts legend with a hat trick of victories over B.J. Penn, Edgar competed in a bantamweight match against Cory Sandhagen at the UFC Fight Night 184 event in Las Vegas.

The bout had barely even started before Sandhagen struck Edgar with a knockout of the year contender, cracking the fighter's jaw with his kneecap so hard that his body stiffened in an instant and he collapsed awkwardly to the floor.

"Props to Sandhagen he landed a perfectly-timed and executed bomb on me," Edgar said on Instagram after the loss.

"Luckily, I don't remember it much lol. This game can be a cruel bitch and Saturday night was just that."

Edgar finished his statement by saying "till the next time, see you soon."

Mixed Martial Arts, the official record-keeper for MMA, sent Insider a document Monday detailing medical suspensions for athletes competing at the weekend's event - the UFC's first show since it returned to the US from Fight Island in Abu Dhabi.

The Nevada Athletic State Commission suspended Edgar until April 8, and banned him from participating in contact sparring until March 24, the list showed.

Medical suspensions for combat athletes who have recently competed are common in the industry regardless of whether they won or lost, and are designed to allow a sufficient recovery period after fighting.

Edgar, for example, is not the only athlete from Saturday's event to be given a medical suspension.

Alistair Overeem, who lost by first-round knockout to Alexander Volkov, is out of action for six months.

Overeem suffered a nose so broken it looked like he was wearing a mask of blood, but the London-born Dutchman can return to action sooner should he receive medical clearance from an ear, nose, and throat specialist.

Though Devonte Smith defeated Justin Jayes, he must have an x-ray of his right hand and wrist and, if there is damage, he'll need orthopedic clearance to fight before August 6.

His opponent Jaynes lost because of a doctor's stoppage after it was ruled a grotesque eye swelling impaired his ability to see, and so he's been suspended until March 9.

The Nevada State Athletic Commission issued suspensions to 16 of the 24 fighters at UFC Fight Night 184.
