Newcastle have signed Danish rider Claes Nedermark to their 2011 roster as replacement for Lubos Tomicek.
Nedermark, 21, has been without a ride after he was dropped from the Plymouth Devils squad ahead of the new campaign after an average mix-up.
"We've had a few problems early on this season, and we've had to take action," club co-owner Darryl Illingworth said.
"We're obviously hoping our tradition of finding quality Danes continues will continue with Claes."
The rider's official website states that Nedermark is on a month's trial at Brough Park.
