Hooker captioned the saddening photo: "So close yet so far!"
ESPN journalist Ariel Helwani shared the image to Twitter, sympathising with the UFC star.
"Man. Can't imagine how difficult this is for Hooker," Helwani wrote.
"Because he flew (and fought) to Vegas, he now has to quarantine for 14 days back home in NZ at a hotel. This is the closest he can come to his family during that two-week period."
MMA reporter Niall McGrath replied: "That sucks, amazing the sacrifice these guys make. Something that's often taken for granted."
Hooker was left with a battered face following Sunday's brutal five-round slugfest. After he was rushed to hospital, the New Zealander posted a video online sporting a heavily bruised face.
"Hey everyone, just back at the hotel with the lads," he said.
"Having a feast, just got checked out of the hospital, everything is all good, just a couple of stitches on the eye.
"But hey, that's the game the game we play no worries.
"Just a small setback and then I'll be back."
Currently sitting at No. 5 in the UFC lightweight rankings, Hooker's professional record stands at 20 wins and nine losses following Sunday's defeat.
