Former Boston Bruins player, Derek Sanderson will be signing copies of his new autobiography, “Crossing The Line” on Saturday at the Barnes & Noble at the Derby Street Shoppes.

Sanderson, who delivered the pass to set up Bobby Orr's famous game-winning goal in the Bruins 1970 Stanley Cup Championship, will only be signing copies of his book and will not be signing any other memorabilia.

“Crossing The Line” shares how Sanderson’s ferocious style helped lead the team to two Stanley Cup victories in the early 1970s.

The signing will run from 3-5 p.m. on Dec. 15 and copies of his book will be available to purchase at the store.
