The result marked the Tigers' first home defeat since 2017 and Silva's first home defeat as a manager in more than three years, and it leaves them just two points above the relegation zone ahead of 18th-placed Swansea City's encounter with Everton this evening.
Hull will be in the dropzone should the Swans win, however, and have only games with Crystal Palace and Tottenham Hotspur left to play in the fight for survival.
"It's disappointing," Silva told BBC Sport. "We had chances to score in many moments of the game. Ultimately there was big tension in some of the team. We need to be calm in some moments.
"When you don't do this you start to lose focus and we conceded two from set-pieces. Now is the moment to rest and analyse. It's an important moment for us. We didn't achieve what wanted from the match but we have two more games."
Hull travel to London to take on Palace a week tomorrow.
