Worcester remain within three points of Championship leaders Bristol going into the final three weekends of the season.
The Warriors' eight-try 56-15 home win over third-placed London Scottish briefly took them back to the top of the table on Saturday evening.
But Bristol responded with a bonus-point victory of their own on Sunday, beating Bedford 38-14.
The two teams are scheduled to meet on the final day of the league campaign at Sixways on 25 April.

Warriors had eight different try scorers in Saturday's triumph.
Stand-off Ryan Lamb, prop Ryan Bower and full-back Chris Pennell crossed before the break, all converted by Andy Symons for a narrow 21-15 interval lead.
But Dean Ryan's men cut loose after the break, scoring five unanswered tries.
Debutant Cooper Vuna, fellow winger Sam Smith, flanker Sam Betty, centre Max Stelling and scrum-half Jonny Arr all scored, Symons adding another five conversions for an individual haul of 16 points with the boot.
