Bernard-Docker was the No.26 overall pick in 2018 and signs with the Senators after three years at the University of North Dakota. The 20-year-old defenseman scored three goals with 15 assists (18 points) in 27 games this season.

Compher was a healthy scratch on Tuesday but will replace Matt Calvert (undisclosed) in the lineup on Thursday. Compher, who has been shifted into a fourth-line role since his return from injury, has just two goals and three assists in 23 games this season.

Watson broke his hand in Monday's win over the Flames and is expected to be out until at least late-April. With Watson out, Alex Formenton will make his season debut with the Senators on Wednesday.

Compher will play for the first time since March 5th. Compher missed some time with an upper-body injury but was held out of Thursday's game as a healthy scratch. Compher, who has two goals and two assists in 21 games, will replace Logan O'Connor and skate on the fourth line.

Gibson did not dress Tuesday in Colorado and is day-to-day with a lower-body injury. With Gibson out, Ryan Miller started and Anthony Stolarz served as his backup. If Gibson misses any time, expect them to continue with that experienced duo.
