The 28-year old striker has been trialling with the MLS club recently with head coach Mike Petke suggesting a deal could quite possibly still be struck.
"Bradley's here. It's still an ongoing thing. I think it's a good sign that he's here," said Petke.
"Nothing's been finalized. I think we're still in talks with not only him but the league and (sporting director) Andy (Roxburgh) and I talking.
"The fact that he's here obviously shows that we're interested in him."
Wright-Phillips, who is the son of former Arsenal great Ian Wright, began his career with Manchester City in 2004 and has since played for such clubs as Southampton, Plymouth Argyle, Charlton Athletic and Brentford (loan).
