"Robyn Regehr — a diehard Saskatchewan Roughriders fan to the core — called an audible Friday night on the proverbial line of scrimmage.

From his summer getaway on picturesque Christopher Lake, Regehr gave his approval to a trade from the Calgary Flames to the Buffalo Sabres.

With a no-movement clause in his contract, Regehr had right of refusal on any deal. After talking to new owner Terry Pegula and general manager Darcy Regier, the rugged blueliner told his agent J.P. Barry to give the Flames approval to make the move.

"Options changed," he said Friday night via text. "And I did decide to waive."

With that decision, Regehr ends his tenure as a Flame. Only Jarome Iginla, with 1,106 games, has made more appearances for Calgary than Regehr.

Since joining the Flames in 1999 — after his rights were traded from the Colorado Avalanche — Regehr suited up for 826 regular-season games.

That's 23 more than Al MacInnis.

Earlier in the day, Regehr denied a request from the Flames to waive his no-movement clause for a move to play in front of Ryan Miller.

"We had something with Buffalo that we were very interested in," Feaster said late Friday."
