The Italian player was provisionally suspended but continued playing after challenging it.

An investigation by the International Tennis Integrity Agency (ITIA) found that Sinner was inadvertently contaminated by his physiotherapist, who had applied an over-the-counter spray containing the substance to a cut on his own hand before treating Sinner.

The ITIA accepted the explanation, ruling the violation unintentional. Sinner was cleared of fault, though he will lose his ranking points from Indian Wells, where he reached the semifinals.
