Kaleta received a major penalty for the hit during Sunday's game that saw Richards hit his head and neck as he sprawled into the boards and to the ice in pain.
Richards, who has 13 points in 20 games for the Rangers this season, did not practice with the team on Monday but is expected to be fine.
Kaleta, who is considered a repeat offender, will also forfeit $76,219.25 in salary, the league said in a statement.
