What happened: David Perron split 2025-26 between the Ottawa Senators and Detroit Red Wings after a deadline trade returned him to Detroit. He completed a two-year, $8 million contract carrying a $4 million annual cap hit.
Why it matters: Perron could ease the immediate pressure on Konsta Helenius, Jiri Kulich and Noah Ostlund to absorb larger roles. His 19 seasons of NHL experience would also add leadership to Buffalo's forward group.
By the numbers: Perron recorded 13 goals and 15 assists in 65 games, including three goals in 16 appearances with Detroit. He has 235 goals and 547 points across 1,239 NHL games.
What to watch: Training camp is the next checkpoint as Perron seeks a contract and Buffalo evaluates its remaining options.
