Alarmed fans quickly took to the comments to express their concern.

One person asked: "How'd you hurt your wrist Jezza?"

Another enquired: "What happened to your hand? That's a suspicious-looking bandage."

Speculation grew as more fans chimed in, with one viewer noticing additional details: "Wrist injury is worrying, tanline on his other wrist too..."

Some suspected the bandage was more than just an accident, with one user hinting at a publicity stunt: "Now the rumours will start from that strategically placed plaster... this fella knows how to play the PR game."

While Clarkson remained silent on the matter, the flurry of comments continued, with one exasperated fan pleading, "We all need to know what's happened to your wrist, man!!!"
