Koepke will be assigned to the AHL for cap purposes but will be recalled prior to Opening Night, per Chris Krenn of the Lightning's official site.
Koepke had a solid 2021-22 season with AHL Syracuse, logging 39 points (20 goals, 19 assists) in 69 games. The 24-year-old rookie will make his NHL debut in a bottom-six role on a talented Tampa Bay team and could have some value in deeper leagues.
