France and Barcelona defender Jeremy Mathieu has been diagnosed with meniscus damage in his right knee, and will require an operation.
Barcelona has confirmed that Jeremy Mathieu will undergo surgery after he suffered knee damage playing for France this week.
Mathieu replaced Patrice Evra at halftime of the 4-2 friendly win over Russia on Tuesday but was withdrawn just eight minutes later with clear discomfort.
The 32-year-old has since undergone tests which have confirmed a partial tear of the meniscus of his right knee. He will have an operation on Thursday.
"The club will subsequently issue a statement to explain the result of this operation," Barcelona confirmed in a statement.
