The Blues announced that defenseman Petteri Lindbohm underwent successful shoulder surgery on Friday but that he will be out for the remainder of the season. The 24-year-old has split the season between St. Louis and their shared AHL affiliate in Chicago. In seven games with the Blues in 2017-18, he averaged just shy of 13 minutes per game of ice time while being held off the scoresheet. At the minor league level, he recorded three points in 23 contests. Lindbohm has spent parts of the past three seasons with St. Louis, playing 40 NHL games in that span.
