While the Cleveland Browns‘ rookies were experiencing their “Welcome to the NFL” moment, veteran left tackle Joe Thomas had his “Welcome to old age” moment.

Thomas – a treat on Twitter – revealed Thursday he was invited to join a rookie dinner with franchise legend Jim Brown in attendance.

Thomas, a veteran of 10 NFL seasons, is apparently easily mistaken for a position coach.
