In a major setback to India's Olympic Games preparation, the national women's 4x400m relay team has pulled out of next month's World Relays in Poland, said a source in the Athletics Federation of India (AFI) on Tuesday.

"The team is unfit. The fastest runner in the squad, Anjali Devi, is yet to recover from an injury she had sustained in March," the source told IANS, explaining the reason for skipping the World Relays.
