Constant concern for Milan

The Guinea left back was withdrawn at halftime with an ankle injury in the 1-0 defeat to Inter, and the Rossoneri will find out next week the extent of the damage.

AC Milan will wait until next week to discover the extent of an ankle injury sustained by Kevin Constant in Sunday's Milan derby.

The Guinea left back was withdrawn at halftime in the 1-0 defeat to Inter at San Siro.

He is expected to undergo tests when Milan return to training next Monday.

Under-pressure coach Massimiliano Allegri will be hoping Constant is fit for the Serie A encounter with Atalanta after the winter break on January 6 as he battles to save his job.

Milan is already without striker Stephan El Shaarawy because of a foot injury, while Robinho (shoulder) and Ignazio Abate (ankle) are also sidelined together with Valter Birsa (thigh) and Matias Silvestre (calf).

Defeat to Inter left Milan, which has won just four league games this season, 13th in the table, five points above the relegation zone.
