The availability for Maple Leafs winger William Nylander for tonight’s series opener against Boston is up in the air. He didn’t take part in the game day skate today and head coach Sheldon Keefe didn’t have any updates. Chris Johnston of TSN and The Athletic reports (Twitter link) that the injury isn’t something he was trying to play through down the stretch (where he struggled, notching just four points – all assists – in his final 11 games). Instead, he woke up with some discomfort on Thursday that has made him uncertain for this one. Despite the late-season struggles, Nylander finished second on Toronto in scoring this season, picking up 40 goals for the second straight year while posting a career-best 58 assists and 98 points.
