There’s not much more than a series of tweets right now, but according to ESPN.com’s Tom Haberstroh, free agent forward Josh Harrellson will have a second workout with the Miami Heat later this week. The Heat still have one roster spot open, and it’s believed they are targeting a big man to improve their frontcourt.

Josh Harrellson (@bigjorts55) announces on Twitter that he’ll be in Miami “for the next nine months.”

Harrellson stuck a “hopefully” in there which might mean a potential contract with the Heat is non-guaranteed. Or not.

Source says Harrellson will work out with the Heat again this week in Miami. Pat Riley wasn’t around for first workout. No deal as of now.
