Leicester's record signing Islam Slimani will miss the FA Cup trip to Millwall to add to the Foxes' striker woes.
The Â£30million forward is out with a groin problem as the Premier League champions look for some respite from their disastrous title defence.
They go to Millwall in the FA Cup fifth round on Saturday just a point above the Premier League's relegation zone having lost five successive top flight games and failed to score in their last six league matches.
Leicester boss Claudio Ranieri suggested Slimani, who has six goals in 18 appearances this term, could even miss Wednesday's Champions League game at Sevilla and he is not prepared to risk him at Millwall, while Leonardo Ulloa is also likely to sit out with a thigh problem.
"He feels something in his groin and we are waiting for him. For this match he is not available," Ranieri said of Slimani.
"He's (Ulloa) started to train but bit properly because always feels something. Today he didn't finish the session and then we have to wait to see him back. I can't tell you something until the medical staff tell me he's 100 per cent fit."
Slimani was a second-half substitute in Sunday's 2-0 defeat at Swansea which dragged the Foxes deeper into relegation trouble just nine months after their shock title triumph.
Their only wins in 2017 have come against Everton and Derby in the FA Cup and Ranieri knows the squad must remain united in their time of need.
"It's difficult to say what's right or wrong. For me it's important to stay close together with my players. We fought last season, fought this season, and will continue to fight mood will change," he said.
"Of course we have to improve a little everywhere - just one per cent in every area and then that becomes a lot of per cents."
