Blues Assign Justin Carbonneau To AHL

The St. Louis Blues have reassigned top forward prospect Justin Carbonneau from the QMJHL’s Blainville‑Boisbriand Armada to the AHL’s Springfield Thunderbirds, the club announced today. The move comes just days after Carbonneau’s junior season ended in a heartbreaking Game 7 loss, but the 19‑year‑old now joins Springfield as the Thunderbirds look to close out their first‑round series against the Providence Bruins.

Carbonneau will join the AHL on the heels of one of the most dominant seasons by any junior forward in 2025–26. The Blues’ 2024 second‑round pick was a force in the QMJHL, leading the league with 51 goals and earning the Mario Lemieux Trophy as the Q’s top goal scorer. He finished his regular season with 80 points and a +31 rating in 60 games, cementing himself as one of the most productive and polished young forwards outside the NHL.

In the postseason, Carbonneau posted 20 points (9 goals, 11 assists) in 17 playoff games, finishing tied for fourth in goals and fifth in points across the entire league. He was consistently Blainville‑Boisbriand’s most dangerous forward, driving offense through pace, touch volume, and a heavy shot that translated seamlessly against tighter playoff checking. Even in the series loss, he looked every bit like a player ready for the next step.

Whether that next step includes immediate AHL action remains unclear. Springfield holds a 2–1 series lead over Providence heading into Thursday’s potential clinching Game 4, and the Thunderbirds have not yet indicated whether Carbonneau will dress. It’s not uncommon for junior call‑ups to spend time practicing before entering the lineup, especially after a deep playoff run that ends with a quick turnaround. Still, Carbonneau’s scoring touch and ability to tilt the ice at even strength give Springfield an intriguing option should they choose to use him.

The assignment also gives the Blues’ development staff a valuable window to evaluate Carbonneau against pro competition before next fall’s training camp. His blend of goal‑scoring instincts, competitiveness, and two‑way detail has already made him one of the organization’s most closely watched prospects, and a late‑season AHL cameo would offer a meaningful benchmark for where he stands in the pipeline.

Carbonneau isn’t the only Blues prospect joining Springfield this week. Defenseman Adam Jiricek, whose OHL season also ended in a Game 7 loss, has been promoted as well. Like Carbonneau, his availability for Game 4 remains uncertain.
