Oskarshamn had a nightmare start to the match as Linköping took the lead immediately through Henrik Törnqvist.
In connection with the conceded goal, goalkeeper Joe Cannata was hit by his own player and fell to the ground.
The impact was so bad that the goalkeeper had to be led off the ice with the help of two teammates.
But later came some reassuring news.
- It's a lower body problem, it looked like the hit hit the head, but that wasn't the problem, says Oskarshamn's coach Martin Filander in C More's broadcast.
The second goalkeeper Tim Juel replaced and shortly afterwards also came the equalizer for Oskarshamn.
Antti Suomela was responsible for a nice pass to a free Cameron Brace who slammed in 1-1.
Turned around after the heavy start
Oskarshamn got air under their wings and in the second period they also got results.
Forward Antti Suomela also scored as he made it 2-1 for the visitors - the Finn's 17th goal of the season.
But Linköping came back quickly.
Christoffer Ehn, who also recently extended his contract with the club until 2027, equalized at 2-2.
But the visitors would emerge victorious from the battle.
In the final period, the match was decided by goals from Smejkal and Ahti Oksanen.
The team's second straight victory in the SHL.
