How long will Zac Rinaldo be suspended for his hit on Tampa Bay's Cedric Paquette?

Last night in Boston, Zac Rinaldo really brought the energy and managed to prod the Tampa Bay Lightning into coming back from a 1-goal deficit to a 3-goal win. Unfortunately, the team paying him to make those game-changing hits is the team that suffered from it. Anyhow, the league will obviously take a look at it. They've just announced it:

Boston's Zac Rinaldo will have a hearing tomorrow for an illegal check to the head of Tampa Bay's Cedric Paquette.
