Trinidad and Tobago coach Leo Beenhakker has voiced concern over the fitness of Marvin Andrews ahead of the World Cup finals.
The Rangers defender limped out of the 2-1 friendly defeat by Wales in Austria on Saturday 10 minutes before the interval.
The 32-year-old registered faith healer has defied medical opinion by playing with a cruciate-ligament problem for over a year for the Light Blues.
Trinidad will face England, Paraguay and Sweden in Group B in Germany - their first appearance in the finals.
But Beenhakker is still not fully convinced Andrews will be among his squad.
He said: 'Normally Marvin would be one of my starting 11, but I have the feeling he's still not fit.
'It's just little things with his knee but he needs more time to recover.
'I can change a player who can't participate because of injury right up until 24 hours before our first match.
'Marvin wants to play and is proud to represent his country. But what I've seen here isn't the Marvin I know.
'I'll wait and hope he'll recover in time and be in Germany with us.'
