Blankenburg signed a professional tryout offer with Toronto on Saturday, per Andre Leal of The Hockey News.
Blankenburg had eight goals and 24 points in 61 regular-season appearances with Nashville and Colorado in 2025-26. The 28-year-old might have a chance to win a third-pairing spot with the Maple Leafs, especially if Chris Tanev (abdomen) ends up needing to miss the start of the campaign.
