Cape Town - Springbok prop Vincent Koch had something of a wardrobe malfunction while on European Champions Cup duty for Saracens over the weekend.
With the scores locked at 21-21 against France's Clermont at Stade Marcel Michelin on Sunday, Koch lost his jersey.
With Clermont on the attack and the match situation as tense as possible, Koch opted to play on shirtless.
Just moments later, he made a massive hit on Clermont flank Perceli Yato to force a knock-on.
Unfortunately, it wasn't enough to prevent Clermont from securing a 24-21 win and Saracens have now slipped to third in their pool.
The defending champions now face a must-win clash against Welsh club Ospreys at the Liberty Stadium in January.
Koch has played nine Tests for the Springboks, well below the 30-Test minimum in order for overseas-based players to be selected for the green and gold.
