Negotiations between him and the team have stalled again and he isn't listed on the 27-man roster that is being hosted at Brazilian club and partner Clube Atletico Paranaense's training facilities and adjacent hotel in Curitiba, Brazil.
Mina didn't play a league match in 2007 season due to complications from an MCL injury he suffered in July, 2006, that required additional surgeries. He came to MLS in 2005 on loan from Ecuadorian club El Nacional and scored seven goals in his first season but played only 16 games in 2006 (three goals, one assist).
MLS teams have inquired about trading for his rights but whether a possible trade might be affecting negotiations isn't known. His base salary last year was $80,000 but FCD and MLS might have to pay him more to convert the loan into a transfer.
