Colombian forward Jose Adolfo Valencia did not train with team Thursday. The 20-year-old has missed three consecutive days of training, raising more questions about his status.



Portland general manager Gavin Wilkinson said the team is still conducting medical tests on Valencia, and he did shed a little light on Valencia's absence and status.



"When you make a significant investment (in a player), if there's one or two small red flags, you need to do your homework," Wilkinson said Friday morning. "There may have been a few small red flags that have been raised and we need to make sure that this player is able to fulfill the terms of his contract with the way his body is and his physical talent."



Wilkinson did not give any indication when - or if - Valencia will return to training.



"I can't say he's going to be back on the field tomorrow," Wilkinson said. "I can't say he's going to be back on the field Monday until we come up with all the final results from the testing that we have been doing."



Considering the level of money involved for players, particularly designated players, Wilkinson said those "small red flags" must be thoroughly investigated.



"What we're doing is making a decision on several different fronts regarding what should we do with the player," Wilkinson said. "How is the small red flag affecting the future of the player in Portland?"
