Calgary Flames prospect Adam Ollas Mattsson has had his time at the 2016 World Junior Championship cut short.
The defenceman, selected in the sixth round of the 2014 NHL Draft, suffered a leg fracture in Sweden's 6-0 win over Slovakia in Saturday's quarter-finals. He will miss the remainder of the tournament as a result.
In five games at the tournament, Ollas Mattsson had one goal, two points, and was a plus-three. He has represented Sweden on multiple occasions, including helping his country capture gold at the U17 World Hockey Challenge in 2013, suiting up for four games at the Ivan Hlinka Memorial tournament that same year, and playing alongside fellow Flames prospect Oliver Kylington at the 4 Nations Tournament last August.
Ollas Mattsson is playing for Djurgårdens IF in the Swedish Hockey League this season, where he has one goal and four points in 22 games.
Sweden, who also announced forward William Nylander will be unable to play in the remainder of the tournament, will face Finland in the semi-finals on Monday.
