The Brynäs goalkeeper had to be replaced with ten minutes left when he seemed to get stuck with his left skate in the ice and got some kind of twist.
I have no idea how he is, but I hope it's okay, says two-goal shooter Oskar Lindblom to TV4 Play about Persson's status.
In came Erik Källgren instead, making a comeback after being absent due to injury.
The semifinal spot is the first for the classic club, which has won 13 Swedish Championship titles, since 2017 when Brynäs made it to the final but lost to HV71.
Going for gold
Now it's all about the gold hunt.
We've been fighting all season and gotten better and better, so it's just a matter of fighting to the end, says Lindblom whose Brynäs won its last Swedish Championship title in 2012.
After the win in Gävle last time, and a 3–2 lead in matches, the regular season-winning newcomer had the chance to decide on away ice in Malmö and took it.
20-year-old defenseman Theo Lindstein slammed in 1–0 with his first playoff goal in his career.
Linus Ölund extended to 2–0 in the second period and when only 47 seconds remained of the middle period, Oskar Lindblom steered in 3–1.
Malmö reduced the lead twice, Lassi Thomson to 1–2 and Robin Salo to 2–3, but each time Brynäs could pull away again.
"Completely perfect"
Oskar Lindblom scored 4–2 and became a two-goal shooter.
It's felt better and better throughout the season. I may not have had my spark with me, but that it comes now is completely perfect, says the Brynäs forward.
Brynäs became the second team after Luleå to secure a semifinal spot. Thus, both the series winner and the runner-up are in the semifinal.
The two other semifinal series, Skellefteå–Färjestad (3–2 in matches) and Frölunda–Timrå (3–2), will continue on Monday evening in Västerbotten and Timrå, respectively.
Malmö was cheered on by a sold-out arena, 12,600 spectators. The underdog team was last into the playoffs, knocked out rival Rögle in the eighth-finals and pushed Brynäs.
