Meanwhile, Butcher is still waiting to hear back from defenders Stevie Hammell and MartynCorrigan, who have been offered three-year contracts, and winger Jim Paterson, offered a two-year deal.
Stefan Klos kept Rangers in front when MartynCorrigan met Steven Hammell's free kick with a header from six yards only for the German to block the effort with his chest.
Lovenkrands had a good chance to double the lead a few minutes later after an intelligent through-ball from Ricksen, but the Dane's shot on the turn was deflected wide by Martyn Corrigan's challenge.
