A goal from each side in the space of six minutes has ensured that Charlton Athletic and Watford head into half-time level at The Valley.
The opening exchanges proved how evenly matched the two sides are but Troy Deeney could have given his side the advantage with a powerful strike from outside the area had it not been for Ben Hamer's impressive reaction save.
Watford started to apply more pressure as the first period went on and the hosts were lucky to escape two goalmouth scrambles without conceding.
However, the Addicks ran out of luck in the 29th minute when Tommie Hoban lost his marker from a corner before heading past Hamer.
Charlton were level just moments later after Dale Stephens released Ricardo Fuller and the striker made no mistake by slotting the ball home to leave Manuel Almunia frustrated in the Watford goal.
Fernando Forestieri was sent off in added time for a second yellow card after he was adjudged to have dived inside the area by the referee.
