SHEFFIELD No.1 Jack Holder has been ruled out of tonight’s (Monday’s) Premiership trip to Ipswich.

The Australian used his quick reactions to lay the bike down to avoid crashing into Patryk Dudek at high speed in Heat Six of Saturday’s Speedway Grand Prix of Poland.

And while he battled on to finish with seven points in Warsaw, he is now complaining of a left leg problem and is struggling to put any weight on it.

Tigers’ bosses have moved to book triple British Champion Chris Harris to guest against his former employers.

IPSWICH: Jason Doyle, Erik Riss, Danny King, Ben Barker, Troy Batchelor, Paul Starke, Danyon Hume.
SHEFFIELD: Chris Harris, Craig Cook, Tobiasz Musielak, Kyle Howarth, Adam Ellis, Stefan Nielsen, Connor Mountain.
