King's Lynn Stars' injury curse has struck again after heat leader Rory Schlein suffered broken leg racing in Poland.

Riding for Lodz, on Sunday, the Aussie started the meeting in great form – registering three race wins before coming to grief in his fourth ride and suffering the break.

Schlein was taken to nearby hospital for examination, and was then transferred to another hospital for an operation, but now faces a lengthy spell on the sidelines.

Lynn have had a torrid time this season with injuries: skipper Mads Korneliussen has only recently returned to the team having broken his shoulder, Simon Stead's campaign came to a premature end when he broke his leg while practising and reserve Nicklas Porsing suffered a broken wrist last month.

The frustration was compounded by the Speedway Control Bureau's decision to dock Lynn points after ruling that they field an ineligible rider, Kozza Smith - guesting for the injured Porsing - in the 47-43 win at Peterborough last month.

Meanwhile, King's Lynn Young Stars have made a team change with locally-based rider Jake Knight coming back into the side to replace Steve Worrall.

Knight, who started the season at the Norfolk Arena, returns to the side having stepped down earlier in the year to concentrate on racing in the Premier League. With his situation changing, Young Stars team manager Dale Allitt had been keeping a close eye on the youngster.

Work commitments and a lack of equipment has forced Worrall to step down. The young Brit, who is based up north, is finding it hard to commit to Wednesday night racing.
