Graves was promoted from AHL Wilkes-Barre/Scranton on Tuesday.
EDGE Analysis
Graves' call-up comes after Erik Karlsson (lower body) was placed on injured reserve. Even with his elevation to the NHL roster, the 30-year-old Graves is far from a lock to play in Tuesday's matchup with the Lightning. In his 17 NHL games this year, Graves has managed just one point, 19 shots and 13 hits.
