Bieksa leads Vancouver's defense in scoring with 11 points in 13 games and the team in average ice time at 24:38. He was hurt by a teammate's shot against Nashville on Nov. 4, but finished that game and played three more before the fracture was discovered on Thursday.
"He d been X-rayed two or three times. The X-ray was showing up nothing," coach Alain Vigneault said. "He still felt pain so yesterday we had a scan done, which showed a hairline fracture."
Vigneault said veteran Rob Davison, a healthy scratch for 12 of 16 games, would take Bieksa's spot in the lineup Saturday against Toronto. The Canucks also recalled defenseman Lawrence Nycholat from a conditioning stint in the AHL on Friday.
Vancouver also expects forward Pavol Demitra back Saturday after he missed 10 games because of rib cartilage he injured in a game Oct. 19. Demitra has three points in six games. He signed a two-year, $8 million free agent contract last summer.
