When Marner was sidelined after a clash with the Boston Bruins on March 7th, Keefe described it as a "day-to-day" issue. However, with Marner still sidelined nine days later, Keefe conceded that the situation has evolved.
Dr. Ali Rendely highlighted that the league's average for recovery from a high ankle sprain is around 8 games, but the range is vast, spanning from zero to as many as 65 games missed. With Marner having missed only two games so far, it suggests he could be out for a considerable period.
