According to Arcinfo, he should be able to return to the Bee's lineup sooner rather than later. Lucas Matewa finished the game against Olten but injured his ankle in the last minute of regulation.
As for Arnaud Jaquet, who is dealing with shoulder issues, he will likely be out of HC La Chaux-de-Fonds for at least two weeks. He, too, suffered the injury in the game against EHC Olten.
