The Croatia midfielder was forced off before halftime in sunday’s 1-1 draw at Euro qualifying opponents Italy.
Modric appeared to have suffered a groin strain, in the 26th minute, after jostling for the ball with an Italian player in the middle of the pitch.
After briefly showing clear signs of pain, he forced himself to try to stop an Italian counter-attack, but he pulled up and then lay on the pitch.
A minor Injury it may seem but should not be underrated as a mere groin injury is capable of giving players unprecedented problems. With this Injury, the former Spurs midfielder is expected to be sidelined for up to 4 weeks.
Luka Modric who has been a key to Real Madrid success lately will be thoroughly felt by the Los Blancos even if it is just for these few weeks.
