Hill: Returns to former club

Both of Bath's changes come in the front row as props Charlie Beech and Duncan Bell come in for Nathan Catt and Anthony Perenise.

Worcester bring Tom Arscott into their side on the wing as Chris Pennell reverts to full-back. Ed Shervington starts at hooker while a virus sees lock James Percival ruled out and Craig Gillies handed a starting role. Back-rower Kai Horstmann could make a first league appearance since September off the bench.

Richard Hill's charges go into the game high in confidence after seeing off defending Premiership champions Saracens 16-11 at Sixways last time.

However, Hill, who is returning his former club, knows it will be tough to pull-off an historic first-ever win at the venue.

"We are looking forward to going down to Bath and trying to maintain our good run of form this year in the Aviva Premiership," he said.

"We know the size of the task that faces us. Bath have been in the Heineken Cup this year, have hit some form in recent times and have a top six squad - there is no doubt about that.

"However, we are brimming full of confidence after our league win over champions Saracens last Friday night and start to 2012.

"We have to go down to The Rec and display that confidence and willingness to play whilst being aware that Bath are a very dangerous team."
