KING’S Lynn’s Lewis Kerr has been ruled out of Thursday’s home clash with Ipswich due to an aggravated collarbone injury.

Kerr made a guest appearance for Plymouth on Tuesday but did not ride in Heat 15 having been signed out of the meeting.

Former Lynn rider Kasper Andersen, who now races for Championship club Redcar, comes in to make a guest appearance for the Minors & Brady Stars and will take Kerr’s No.6 position.
