Alexeyev (personal) was back with the Capitals ahead of Thursday's clash with Montreal, Tarik El-Bashir of Monumental Sports Network reports.
Alexeyev will slot into the lineup for Washington for the first time this season due to injuries to Matt Roy (lower body) and Jakob Chychrun (upper body). Since both injured players still sported non-contact jerseys at Thursday's game-day skate, the 24-year-old Alexeyev could also be pressed into service for the Capitals' upcoming back-to-back versus Columbus and Carolina on Saturday and Sunday, respectively.
