A close contest between the teams at Kingsholm Stadium on Saturday saw the visitors come out 22-16 winners.
"We've got to lick our wounds a little bit," Davies told the league's official website. "And we are wounded - we're humiliated.

Gloucester have the chance to return to winning ways next Sunday when they travel to Saracens.
