More Premiership clubs are joining the race for Rangers striker Kris Boyd.

The Daily Mail says Hull City and West Ham United could join the growing Premiership race for Boyd - with Aston Villa and Birmingham City already keen on landing the Rangers striker.

Boyd is understood to have visited Villa Park for Wednesday night's Carling Cup semi-final win over Blackburn Rovers, with preliminary discussions taking place over a possible precontract offer for a summer switch.

Birmingham boss Alex McLeish, who has a transfer war chest after new owner Carson Yeung promised him £40million to spend on the Premier League high-fliers, is closely monitoring the situation, while Hull and West Ham, another club with new owners following David Sullivan and David Gold's recent buyout, are also understood to be considering making moves towards making Boyd a Bosman acquisition.
