The Toronto Maple Leafs' William Nylander is on the brink of returning to the lineup for Game 4 of the Stanley Cup playoff series against the Boston Bruins on Saturday after being sidelined for the first three games due to an undisclosed injury.

• Nylander was a full participant in practice on Friday and skated with regular linemates, indicating his readiness to return.
• Toronto is trailing Boston 2-1 in the series and could benefit from Nylander's offensive prowess, especially on the struggling power play.

Details of Nylander's injury have been kept private by the Leafs, and Nylander himself chose not to confirm reports of dealing with migraines.

• Coach Sheldon Keefe expressed optimism about Nylander's return after a positive practice session, hinting at his potential availability for Game 4.
• Boston may switch goaltenders for Game 4, with uncertainty over whether Jeremy Swayman or Linus Ullmark will start.

If Nylander returns for Game 4, it could significantly impact Toronto's offensive capabilities and their chances of leveling the series before Game 5 in Boston.

William Nylander's potential return presents a crucial opportunity for the Toronto Maple Leafs to enhance their scoring power and potentially turn the series tide against the Boston Bruins.
