PREMIER League champions King's Lynn track Elite League ace Chris Kerr for injured skipper Tomas Topinka in Wednesday's Premier League play-off semi-final, second leg against Birmingham at the Norfolk Arena (7.45pm).

Kerr rode for Wolverhampton in Monday night's Elite League grand final clash against Swindon and the American has agreed to step in for Topinka who has been ruled out of Lynn's run in after suffering concussion in a heavy tumble at the Czech Golden Helmet meeting.

Team boss Rob Lyon is taking nothing for granted despite the club's 47-43 first leg success at Perry Barr with Edinburgh awaiting in the play-off final.

Lynn officials have already confirmed the treble-chasing Stars will travel north of the border this Friday to tackle the Monarchs if they manage to complete a Saddlebow semi final job on Birmingham.

“If all their riders click at the same time then they could blow us away,” warned Lyon. “Just as they did last season when they pulled off the shock result of the decade and beat us at home. At the end of the day this could possibly be their last meeting of the season so they have nothing to lose and I fully expect them to come and throw everything they have at it.”

The Brummies track Corey Gathercole for suspended number one Tomasz Pisczc. The Aussie joins compatriots Richard Sweetman, Rusty Harrison, Jason Lyons and Lee Herne in the visiting line up.

Lynn beat their Midlands' rivals to lift the Premier Trophy but Stars' chief Buster Chapman admits Topinka's injury absence is a blow to hopes of play-off and KO Cup success.

“Tomas has been such a big part of all the trophies we have won here over the past five seasons,” said Chapman. “To have him out injured has somewhat dampened the spirits of the team, I know he wants us to carry on as normal but that is a hard thing to do, I really hope we see him back here in the pits soon.”

Parade 7.30pm, first race 7.45pm.
