SUNDAY's episode of Celebrity SAS saw a total of three recruits depart the gruelling programme.
It means just four famous faces remain heading into the final stages.
The latest episode saw Bobby, 38, depart after a doctor recommended his exit following a wrestling match.
He took on towering basketball player Ovie Soko, who won the bout and ripped Bobby's shirt.
The tough challenge recruits were tasked with wrestling an opponent and getting them outside a makeshift ring filled with mud.
Afterwards, Bobby requested a medic and was sent to a doctor who said he needed to medically withdraw him from the show.

The medical professional said Bobby had "a lot of spasm" going down his neck which was "likely to increase".
He added: "Your mobility is going to get more restricted, and you're going to be at risk of doing yourself more damage."
Former professional boxer Anthony Ogogo was the last competitor standing after all six recruits faced off in the ring.
Meanwhile, the Channel 4 show's latest episode also saw Love Island star Ovie and presenter Cherry Healey exit.

Cherry, 43 was the first to bow out during Sunday night's instalment.
She told instructor Jason Fox: "It's been life-changing, but I know when the line is and that's fine. I thought about this long and hard."
As for Ovie, he left while "on the run" in a challenge that split the recruits into two teams.
The groups' aim was to find their way to safety in the middle of the night.
In the meantime, they were being pursued by a hunter force made up of ex-military members.
Speaking to reality star Georgia Harrison, Ovie said: "I'm done... I'm going to hand my armband in."
Sunday night's episode also saw the recruits given a chance to speak to their loved ones.
