Swindon have been hit by a major injury setback ahead of their clash with Belle Vue at the Abbey on Monday.
Polish star Tobiasz Musielak, recently back in action after shoulder problems, was involved in a heavy pile-up during the Lodz v Tarnow fixture in his home country on Sunday.
Musielak is heading back to Leszno for assessment of the full extent of the damage, but early indications are that he has suffered a serious knee ligament injury and faces an extended period out of the saddle.
Robins boss Alun Rossiter said: “It really goes from bad to worse, and unfortunately it looks like it’s an injury where there’s no quick fix.
“I’ve done knee ligaments myself and I know from that experience that it could turn out to be season-ending.
“Obviously it means we have to take some big decisions regarding the team, although we have no option but to run rider-replacement on Monday.
“Tobiasz is fourth in the averages so we have no choice in that, and even if we could use guests the choice is very limited with the fixed race-nights.
“So we have to look what route we’re going to go down, whether a 28-day deal or something more long-term than that, and we are straightaway on the lookout for someone to come in.
“In the meantime we need everyone firing tomorrow against Belle Vue, which was already a tough match, and we have to rise to the occasion.”
Everyone at Swindon Speedway sends Tobiasz their best wishes for hopefully as speedy a recovery as possible.
