John Ludvig, a 24-year-old defenseman, was claimed by the Colorado Avalanche after playing 33 games for the Pittsburgh Penguins last season. He recorded 5 points and accumulated 47 penalty minutes during his time with the Penguins. Previously, he was waived by the Florida Panthers before joining Pittsburgh. With his addition, Ludvig is expected to be one of eight defensemen on the Avalanche's opening night roster.
