Graham has been invited to Vancouver's training camp, TSN reports.
The 24-year-old defenseman spent last season in AHL San Antonio, where he tallied 21 points in 46 games. Unlikely to crack the Opening Night roster in Vancouver, Graham will likely wind up playing for AHL Utica in 2018-19.
Graham was placed on waivers Monday, Renaud Lavoie of TVA Sports reports.
The blueliner has split each of his three pro seasons between the AHL and lower-level ECHL, but is likely to spend the entirety of 2017-18 with AHL San Antonio.
