The 30-year old, who was recently released by English League Two club Bradford City, has had one session with the Quakes and says he is looking to make the most of the opportunity.
"I'm delighted for the opportunity to train with the team," said Daley.
"My first training session, I really enjoyed today. So we'll hopefully see what happens over the next couple of days."
Daley, who has also played for Reading and Preston North End, was a key member of the Jamaican team at this summer's CONCACAF Gold Cup and is no stranger to US soccer as he spent about a year with USL Pro team Charleston Battery a few years back.
