Foxes duo sit out Carling Cup clash
Defender Tunchev is on international duty with Bulgaria and midfielder King is away with the Wales Under-21 squad.
But the Foxes will be boosted by the availability of on-loan striker Martyn Waghorn, who has been given permission to play by his parent club Sunderland.
Waghorn, who scored in Saturday's 2-1 win against Swansea, was also on standby for the England Under-20s, but has not been called up.
Full-back Robbie Neilson serves the second game of his two-match ban after it was confirmed he would miss the cup tie, rather than Saturday's Championship trip to Ipswich.
