Matthews will not attend the World Championship in Denmark next month, Kristen Shilton of TSN.ca reports.

EDGE Analysis

This is bad news for Team USA, but Matthews experienced upper-body and shoulder injuries this season, and he probably could use a mental break after the Maple Leafs lost to the Bruins through seven games of a grueling first-round playoff series. In his second NHL season, the puck prodigy notched 34 goals, 29 assists to complement a shiny plus-25 rating and 13 power-play points during the regular season, though Matthews looked a step slower in the conference quarterfinals and wound up with only two points and a minus-4 rating.
