The NFL Players Association received the official letter from the league confirming Ray Rice's indefinite suspension, according to ESPN.

This letter outlines the league's rationale for its decision to change Rice's original two-game suspension to the current one in the wake of the video release by TMZ on Monday showing Rice striking his then-fiancee Janay Palmer and knocking her unconscious in the elevator of the Revel Casino Hotel in Atlantic City.

The league's official explanation to the Players Association about Rice's indefinite suspension offers another important detail in trying to determine how much the NFL and the Ravens knew about what happened in February and how the full video of the assault figured into their decision.
