Competing at the 2020 European Championships, Březina placed first in the short program despite performing only a quad-double as his combination jump, winning a gold small medal. He said he was undecided as to whether it would be his final competition. He fell twice in the free skate on quad Salchow attempts, placing eleventh in that segment and falling to seventh place overall. He was scheduled to compete at the 2020 World Championships in Montreal, but these were cancelled as a result of the COVID-19 pandemic.
