Wahlberg signed a three-year, entry-level contract with Buffalo on Friday.
Wahlberg was chosen 39th overall in the 2023 Draft. The 18-year-old had a pair of goals and two assists in 17 games with Malmo of the Swedish League last season. The center also chipped in with three goals and six points in seven games at the U18 World Championship in the spring. Wahlberg likely won't light up the scoresheet at the NHL level, but he has the potential to carve out a role as a bottom-sixer.
