With Pochettino's men pushing for a winner, the Brazilian striker's efforts saw Spurs go down to 10 men. This did not deter the visitors, who still aimed for a win at Vicarage Road.
Tottenham had managed to set up camp in the Watford half after the break, but the home side were a threat on the break. Sanchez was surprised by Richarlison's speed and the defender put a horrendous elbow in the forward's face.
The raised arm saw Atkinson pull out the red on advice from his assistant.
