Oscar Cordoba to quit at end of season
The 39-year-old, who won more than 70 caps, hurt his leg in a 1-0 defeat at Pereira in the Clausura championship on Sunday.
"I've had lots of injuries this last year and my back problem is already chronic so this season is my last. I don't see any other outcome," Cordoba told reporters on Thursday.
"It's incredible, two months don't go by before I'm injured again. It saddens me," said the former Boca Juniors and Besiktas goalkeeper.
"If Millonarios reach the semi-final (knockout phase) it would be an excellent way of saying goodbye," added Cordoba who said he would need two weeks to recover from his latest injury.
Millonarios are 10th in the standings with two matches to go. The top eight qualify for the knockout phase.
Cordoba, who helped Colombia win their only Copa America at home in 2001, won the domestic league with America in 1997.
He then became part of a successful Boca Juniors side that won the South American Libertadores Cup in 2000 and 2001 and the Intercontinental Cup, now the Club World Cup, in 2000.
