The Rimouski Oceanic have acquired Washington Capitals prospect Eriks Mateiko from the Saint John Sea Dogs.

In return, the Sea Dogs received four QMJHL draft picks.

The 108th pick in the 2022 CHL Import Draft, Mateiko played 134 games with the Sea Dogs and tallied 98 points.

Mateiko recently represented Latvia at the 2025 World Juniors where he had five goals in five games as they reached the quarterfinals.
