Who was the last linebacker to play without a facemask?

The last linebacker known to play without a facemask in the NFL was Chuck Bednarik. He played for the Philadelphia Eagles from 1949 to 1962 and was renowned for his tough playing style. Bednarik famously wore a single-bar helmet, which was characteristic of that era, before facemasks became standard equipment for players. His era marked a transition in football equipment, and he is often remembered as one of the last players to compete without a facemask.
