"I think this is a good week for Juan," Heaps told MLSsoccer.com of the promising USA international.
"He joined us last week and he only had two half-days of training that weren't real. It would have been a tough decision to have him to go full without having a week with us.
"We're training him this week. We're getting him back to see where he is [in terms of his] fitness level. He hasn't played in three weeks, from a fitness standpoint, but he's healthy and he's moving around.
"This week will be important to gauge him."
