Reed was suspended for one game without pay on Monday by NFL vice president of football operations Merton Hanks for his third violation in three seasons of the rule prohibiting helmet-to-helmet hits against defenseless players. The third violation occurred in Sunday night's game at Pittsburgh: Reed's hit to the head of receiver Emmanuel Sanders.
Reed appealed the ruling in a phone session Tuesday morning with NFL hearing officer Ted Cottrell. The NFL Players Association represented Reed, who also participated.
Hours later, Cottrell reduced the penalty.
In a letter to Reed, Cottrell wrote: "I have determined that your actions were egregious and warrant significant discipline. However, I do not believe that your actions were so egregious as to subject you to a one-game suspension without pay. Player safety is the league's primary concern in the formation of playing rules and all players are expected to adhere to those rules or face disciplinary action. I hope in the future you will focus on ensuring that your play conforms to the rules."
Reed will be in uniform for Sunday's game in San Diego. Reed would've lost his game check of $423,529 had his suspension remained in effect.
"The league has an appeal process to review situations like this, and Ed had his opportunity to answer questions about his play," Ravens general manager Ozzie Newsome said in a statement. "I think John (Harbaugh) and his coaches do an excellent job of teaching the right, safe and legal way to play football, and we believe Ed clearly tries to play within the rules on every down."
