on 31 August 2019. The game ended as a 3–0 DC win. During the 2019 season, Kamara suffered a hamstring injury. He then returned from injury coming on in the 69th minute in a crucial game against FC Cincinnati on 6 October 2019. The crucial game ended 0–0, crushing United's hopes of hosting a round one MLS playoff game. DC had to travel to Toronto for the first round of the 2019 MLS Cup Playoffs and were defeated 5-1 after giving up 4 goals in AET to end their season. Kamara's 2020 season was extremely disappointing, although the COVID-19 Pandemic did cause a break in the MLS season and subsequent rearrangement of the schedule. He played in 22 of D.C.'s 23 regular season matches and started 17 but only managed to net four goals and did not provide a single assist. Kamara did score on the final day of season in the 33rd minute to give D.C. a 2–1 lead over Montreal Impact but two late goals by the Impact to turn the match around denied D.C. a second straight playoff appearance. The 2021 Season did not start on a high note for Kamara. Due to a preseason injury setback he missed D.C.’s first three matches and was limited to 90 minutes total in his next four. He caught fire, however, during the summer months as he scored 13 goals in 14 matches in July, August, and September. He also lead the league in G/90 with 0.94. On the final day of the season Kamara scored a brace in a 3–1 win against Toronto FC which pushed him into a tie at the top of the 2021 MLS Golden Boot standings. Ultimately, though, he lost out to Valentin Castellanos due to the assist tiebreaker. That hurt was coupled by the fact that even though D.C. won their final match, other results did not go in their favor and they missed out on the 2021 MLS Cup Playoffs by one point. Kamara started his 2022 season with a goal in D.C.'s 3–0 win against new-comers Charlotte FC on February 26. International career Kamara was eligible to represent either Norway or Sierra Leone national teams at international levels, as his mother is Norwegian and his father Sierra Leonean. Kamara was selected for regional teams () in Oslo at the age of 15, and later represented Norway at under-16 and under-17 level. He
