Check out this video Luca posted Saturday to his Instagram ... it shows him seated in a wheelchair as he's being carted through the medical facility with his extended leg in a brace while gripping a pair of crutches.

Bish did not provide details on how he suffered his injury, but he added a touch of humor to his painful sitch by playing Ed Sheeran's song, "Thinking Out Loud," which includes the lyrics: "my legs don't work like they used to before."

As you may know, Luca appeared as a contestant on Season 8 of "Love Island," which brings together singles looking for love while living together in a luxury villa.

To stay on the show, the players forge romantic relationships to see if they are a good fit as the public gets to vote who stays on the island and who gets booted.

Luca made it pretty far in the process, getting crowned runner-up with Gemma Owen, the daughter of ex-British soccer player Michael Owen. But, Luca and Gemma split after three months.
