FA official Leigh Dought gave nothing as both Luton Town players and fans called for the foul play.
Carlton Morris scored the only goal of the game as the Hatters continue to chase promotion to the Premiership with a 1-0 victory over Sheffield Utd at Bramall Lane.
Morris has now helped Luton win three out of the past 4 league games in the Championship as they attempt to cement a permanent playoff position.
Despite winning the match - Luton fans are still not willing to let go of the foul on Lockyer.
Luton fans are calling for a ban/suspension for Sharp however nothing has been addressed either clubs as of yet.
This being one of the many fouls seen on a weekly basis in the EFL which officials refuse to entertain despite most evidence and appeals.
Regular incompetence the referees in the EFL continue to cost it's competitive clubs' potential points, both up and down their respective leagues.
Fortunately for Luton Town they still managed to take all three points this time around.
