Harkins scored two goals on four shots and added six hits in Thursday's 5-3 preseason loss to the Panthers.
Harkins was signed to fill a bottom-six spot for the Lightning. Any offense is a bonus, but he showed some spark plug capabilities in this preseason contest. Don't expect a lot of offense from the 29-year-old -- he's never had more than 13 points in a single NHL campaign, and that came over 77 games with the Jets in 2021-22.
