"What?" and swiftly handed out another yellow card for dissent.
The only game in the Vanarama National League South on Tuesday night saw Hemel Hempstead Town move up to fifth after a 2-0 win against mid-table East Thurrock United at Vauxhall Road.
"Watt", the former Arsenal striker said, before a freaky back and forth which led to him receiving a red card while playing for Hemel Hempstead Town in the National League South.
Eventually, Watt's teammate, captain Jordan Parkes, explained to the referee that Watt's name is Watt.
When referee Dean Hulme asked the number 10 for his name to put it in the book he thought the 27-year-old was expressing dissent by saying "what".
Watt was then sent off for dissent, not having done anything wrong.More news: Bears apply transition tag on CB Fuller
Speaking to the BBC afterwards, Hemel Hempstead chairman Dave Boggins revealed that referee Hulme apologised for the mix-up.
"The referee was man enough to rectify it".
A nomadic career has taken Watt from Arsenal to Colchester, Indian side Kerala Blasters, Crawley Town, Billericay Town and now Hemel Hempstead.
"He was very apologetic and saw the amusing side of it", Boggins said of referee Hulme.
They wrote: "Red card: Sanchez Watt is sent off, presumably for dissent".
"Watt a mistake to make".
