Speedway: Ipswich Witches add four to 2012 line-up
Ipswich Witches have unveiled Taylor Poole, Morten Risager, Dakota North and Mat Tressarieu as 2012 riders.
The quartet join captain Kevin Doolan and young Australians Cameron Heeps and Rohan Tungate at Foxhall.
Team manager Pete Simmons said: "I'm really looking forward to working with this great bunch of lads next season.
"The whole of the squad can easily up their starting averages to give us an excellent chance of improving on last year's Premier League debut season."
