The Witches won 50-40 at Poole Pirates in May

Ipswich will be without Polish riders Jarek Hampel and Robert Miskoviak when they travel to Elite League leaders Poole Pirates on Wednesday.

Hampel is ill while Miskoviak is required by his Polish club and will miss Thursday's meeting with Lakeside.

The Witches will use a rider replacement for Hampel while Somerset Rebels' American rider Brent Werner will guest for Miskoviak.

Meanwhile Piotr Swiderski faces a fitness test.

The Pirates will also use a rider replacement for Dave Watt, who was injured during their Elite League defeat at Peterborough on Monday.

Ipswich, who have already won at Wimbourne Road this season, will be looking to overtake third-placed Swindon.
