Bieksa was hurt blocking a shot Tuesday in Minnesota, but finished the game before tests Wednesday revealed the injury. X-rays were negative, but Bieksa said Thursday in Nashville that a CT scan showed a small break. He will be re-evaluated when the Canucks return to Vancouver and says there's no timeline for his return yet.
The Canucks called up rookie Evan Oberg from the American Hockey League to take his place in Nashville on Thursday night.
Bieksa is the fourth Canucks' defenseman in the last five games to get hurt, and the sixth to be knocked out of action the last three weeks.
