Gasol, 39, signed a one-year, $2.57 million free-agent deal with Portland during the summer. That came after he missed a majority of last season with a foot injury.
As the report notes, Gasol has been unable to successfully rehab from that foot injury and the ensuing surgery.
A six-time All-Star and two-time NBA champion, this could very well be the end of the line for Gasol. If so, he ends a stellar career having averaged 17.0 points and 9.2 rebounds in a whopping 1,226 games.
