Boychuk's most recent eye injury, the second to the same eye in his career, happened March 3, when he was hit by the skate of Montreal Canadiens forward Artturi Lehkonen.
A skate clipped the veteran blue-liner's face during a game in March, requiring 90 stitches to fix the cut. The pandemic shut down the league nine days later as he was preparing to return.
Boychuk returned for the playoffs in August before sustaining a head injury in the preliminary round series opener against Florida.
A standout with the P-Bruins in 2008-09, Boychuk made his full-time jump to the National Hockey League the following season, and was part of the team's Stanley Cup team in 2011 and on the 2013 team that came up short in the 2013 Cup Final.

Boychuk spent the last six seasons with the Islanders, who acquired him in a 2014 trade with the Boston Bruins.
The Colorado Avalanche selected Boychuk 61st overall in 2002.
Known for his ability to tee up blistering and accurate slap shots, the longtime rearguard produced 54 goals and 206 points in 725 contests.
