Arsenal forward Alexis Sanchez will miss the Gunners' Premier League trip to local rivals Tottenham Hotspur on Saturday with a hamstring problem.
The Chile international, 26, has scored 18 in all competitions since his £35m summer arrival from Barcelona.
"He is not far away, the Leicester game on Tuesday is a possibility," boss Arsene Wenger told Arsenal's website.
Striker Danny Welbeck has recovered from a thigh injury and will feature for the first time since 28 December.
Fifth-placed Arsenal will also have to make do without midfielders Jack Wilshere and Alex Oxlade-Chamberlain, who are both yet to return to full training following injury lay-offs.
Tottenham are one place and two points below their rivals in the table.
