EDGE Analysis
After head coach Phil Housley announced that the Swede would miss four-to-six weeks with his ailment, this transaction was always a formality. Josefson has been hampered by injuries all of 2017-18 but still notched two points in nine games so far during his first season with Buffalo, and will likely return around the New Year.
