Keith is in Cyprus with the Ireland U19 squad for a mini-tournament and Robbo is suspended after picking up five bookings. However, Kevin Foley is likely to slot back in to his right-back position in the absence of Keane.
Mike Newell has many options to take Robinson's place, with the most likely being Michael Leary, who recently scored his sixth goal this season for the reserves. However, Stephen O'Leary might be in with a chance and even Gary McSheffrey might be given a start. Saturday's game is due to be McSheff's last game before he is due to return to Coventry, and he is unsure whether to extend his loan deal at Luton.
