Wilson was ejected from Sunday's preseason game against the St. Louis Blues for an illegal check to the head on Oskar Sundqvist. After the hit, Sundqvist laid motionless on the ice and had to be helped off it.
The in-person hearing means the NHL can suspend Wilson for six or more games. The time and date of the hearing -- and whether Wilson will elect to have it in-person -- have yet to be determined.
Wilson, who plays on Washington's top line alongside Alex Ovechkin, was suspended on three occasions last season. That includes a three-game suspension in the second round of the playoffs against the Pittsburgh Penguins for an illegal hit on Penguins forward Zach Aston-Reese. On the play, Aston-Reese was concussed and also suffered a broken jaw.
Wilson's status as a repeat offender likely will factor into the NHL Department of Player Safety's decision. Injuries to the player on the wrong end of the hit are also considered when determining supplemental discipline.
Wilson signed a six-year, $31 million extension this offseason to remain with the defending Stanley Cup champions. Washington will raise its Stanley Cup banner on Wednesday when it hosts the Boston Bruins in the regular-season opener.
