Canucks president Trevor Linden revealed in a press conference Tuesday that Sedin suffered a broken finger at some point during the campaign, but played through it.
Linden didn't indicate when the injury occurred.
Sedin's 74 games played were the second-lowest total for him over an 82-game season. His career low came in 2013-14, when he suited up for 70 contests.
The 35-year-old still topped 50 points for 10th time in his career, totaling 55.
