Inter Milan's Yuto Nagatomo is set to miss the next three weeks with the knee injury he suffered in the Milan derby.
The Japanese defender was substituted after 76 minutes as Inter held rivals AC Milan to a 1-1 draw on Sunday.
Nagatomo, 26, is likely to miss both legs of the Europa League tie with Tottenham as well as several Serie A fixtures.
Following initial fears that Nagatomo would have to sit out the rest of the season, Inter announced that the injury was not serious enough to warrant surgery.
A club statement read: "The outcome of the tests carried out was that he has a capsular ligament injury to the external meniscus and minor damage to the external ligament."
