The Maple Leafs will be without top center Auston Matthews tonight against the Islanders, reports Chris Johnston of TSN and The Athletic (Twitter link). Matthews is believed to have re-aggravated the upper-body injury that kept him out for several games last month, one that continues to linger. Despite playing at less than full health, Matthews has been quite productive when he has been in the lineup, notching 11 goals and 12 assists through 24 outings while averaging over 20 minutes a night for the sixth straight season. Johnston adds that Matthews is listed as questionable for Monday’s contest against Winnipeg but with the break coming up after that, it might make more sense for them to shut Matthews down for that game and give him more time to heal.
