Injured drag-flicker Sandeep Singh was on Saturday ruled out of the Champions Challenge I hockey tournament in Argentina next month and will be replaced by Diwakar Ram in the 21-member Indian squad.
The former skipper, suffering from an acute lumbar strain, has been advised rest for at least three weeks.
"Drag-flicker Sandeep Singh has been medically ruled out for the FIH Men's Champions Challenge I Hockey Tournament to be played at Salta, Argentina from December 6-13," Hockey India said in a statement.
