Gustafsson notched an assist, four shots on goal and two blocked shots in Monday's 4-0 win over the Senators.
This was Gustafsson's first point in his last seven appearances. The 32-year-old defenseman ends the regular season with 31 points, 93 shots on net, 66 blocked shots, 63 hits and a plus-3 rating over 76 appearances. He'll likely remain in a bottom-four role as a power-play specialist to begin the playoffs.
