Olofsson, who paced the SHL with 27 regular-season goals, ends the playoffs with four points (3+1) and 19 shots on goal while averaging 17:04 of work per contest.
Rasmus Asplund (2016, second round) was unable to get a point as Farjestad BK clawed their way back with back-to-back victories in their series against Skelleftea AIK but saw their season end with a 5-2 loss in Game 6.
Asplund recorded 10 shots on goal and a minus-3 rating in the series' six games.
Following their losses, both Asplund and Olofsson were named to the Sweden's roster for the Euro Hockey Cup, a preparatory tournament in advance of the IIHF World Championship. Sweden will take on Slovakia in pair of games on April 5 and 6.
