Mexico fear that key striker Jared Borgetti could miss the remaining group games against Angola and Portugal after limping out of Sunday's 3-1 victory against Iran.

The Mexican team doctor, Jose Luis Serrano, has confirmed that the 32-year-old Bolton Wanderers forward suffered a hamstring injury in the game.

"It seems like we have a serious injury," he said.

"On Tuesday we are going to carry out an examination. Injuries like this could take seven to ten days to heal."

Borgetti was the leading scorer in the CONCACAF qualifying zone and has an impressive goals to games ratio that sees him register once every other appearance on average.
