Rosenberg, 22, took two golds in the U23 World Championship, sprint and 20 kilometer mass start. Grahn, 20, also came home from the championship with a sprint gold.
During the winter, both have also reached the semifinals in a World Cup sprint for the first time in their careers.
The performances are enough to, almost, secure a spot in the Swedish team for the World Championship in Trondheim. Along with Gustaf Berglund, 26, and Truls Gisselman, 23, Rosenberg and Grahn are selected as reserves.
"We have selected four reserves who will be on site at the World Championship during different periods. We have also registered several names that can become reserve options, but only if illnesses or injuries occur", says national team manager Anders Byström in a press release.
The World Championship opens next Wednesday and runs until March 9.
