Bruins' Vaakanainen suffers concussion after taking elbow to face

Boston Bruins rookie defenseman Urho Vaakanainen suffered a concussion during Tuesday's contest against the Ottawa Senators and will not return after catching a Mark Borowiecki elbow in the face, the team announced.

The game was just the second of Vaakanainen's career. He was recalled from the AHL last week.

If Vaakanainen were to miss additional time it would be a significant blow to a Bruins blue line already without Torey Krug, Charlie McAvoy, and Kevan Miller.

Vaakanainen, 19, was the Bruins' first-round pick, 18th overall, in the 2017 NHL Draft.
