The trio began Thursday's Europa League clash at Braga on the bench but came on during the second half as the Foxes came from behind to earn a 3-3 draw and seal qualification for the next round. Wesley Fofana and Nampalys Mendy were also rested in Portugal, with Fofana playing 45 minutes and Mendy an unused substitute, having started the Premier League defeat to Liverpool, and they too could also be recalled.
Midfielder Wilfred Ndidi, out since September with a groin injury, could return against Zorya Luhansk in the Europa League next week while right-back Ricardo Pereira, absent since March with a serious knee injury, is also making progress in his recovery.
