Del Zotto has been healthy scratch for the last two games but will replace Jack Roslovic in the lineup on Saturday. Del Zotto has two goals and five assists in 35 games this season.
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.
Gaudette was on the ice for the start of Tuesday's practice but was pulled immediately once the results of his test came back positive. Gaudette will undergo further testing to determine if it was a false positive but this doesn't bode well for him playing on Wednesday.
Highmore replaced Dylan Strome in the lineup on Sunday but they will swap spots on Tuesday. This marks the fifth time in seven games that Highmore will be a healthy scratch.
Amadio had a career-high 16 points (6G / 10A) in 58 games a season ago but was held without a goal and just two assists in his first 20 games of 2021. In Ottawa, he will likely fill Artem Anisimov's fourth-line/reserve role after Anisimov was placed on waivers.
Ullmark has been out since February 25th but appears set to start Saturday vs. the Bruins. Ullmark was steady early in the season, going 5-4-2 with a 2.44 GAA and .919 SV% but the wheels have completely fallen off in his absence.
Larsson was one of four Ducks' players that was added to the COVID-19 protocol list on Tuesday, putting Wednesday's game in jeopardy. Larsson was a healthy scratch on Monday, so expect him to sit out for a second straight game on Wednesday.
Gregor plated 7:42 TOI on Saturday but will be scratched for the third time in four games on Monday. Alexander True will replace him on the fourth line.
Ullmark was hurt while making a remarkable save on Thursday and keeping the puck out of the net will cost him at least one month. With Ullmark out, Carter Hutton will become the Sabres' No.1 netminder with Jonas Johansson serving as the No.2.
