It's unclear at this time if this just a move to help the Canucks accrue cap space, as they've done all season, especially since now there's 14 forwards on the NHL roster.
For Di Giuseppe and Karlsson, this is their first call-up to the National Hockey League this season and they both saw some time in Vancouver last season, especially the former, who skated in 51 games with the Canucks.
In four games this season for Abbotsford, Di Giuseppe has no points, two penalty minutes and is a minus-one, meanwhile Linus Karlsson has registered six points (five goals, one assist), four penalty minutes and is a plus-three in seven contests.
