Inter's Milito diagnosed with left thigh strain

Milito, who only returned to action for the Serie A giants last month following a seven-month lay-off, limped out of a training session on Wednesday evening.
The 34-year-old striker underwent scans on Thursday morning which revealed he had suffered a "thigh strain (rectus femoris) in his left leg", according to Inter.
The rectus femoris is one of four quadricep (thigh) muscles, all of which are attached to the knee cap.
"Diego Milito underwent scans at the Columbus Clinic this morning, which showed a thigh strain (rectus femoris muscle) in his left leg. The striker has already begun his recovery programme," read the statement.
Inter did not speculate on when Milito would return to Walter Mazzarri's squad, but the fact he has suffered the injury on his left leg will be a concern for club bosses.
The Argentinian suffered a horrific left knee injury earlier this year and after a seven-month recovery only returned to the fray last month when he came off the bench to score a brace in a 7-0 away rout at league new boys Sassuolo.
