You are talking about " reckless manner " in this case.
I think the referee applied the " serious foul play/using excessive force " rule in this case.
From FIFA Rule Book:
Sending-off Offences
A player, substitute or substituted player is sent off if he commits any of the
following seven offences:
• serious foul play
• violent conduct
• spitting at an opponent or any other person
• denying the opposing team a goal or an obvious goal-scoring opportunity
by deliberately handling the ball (this does not apply to a goalkeeper within
his own penalty area)
• denying an obvious goal-scoring opportunity to an opponent moving
towards the player’s goal by an offence punishable by a free kick or a
penalty kick
• using offensive, insulting or abusive language and/or gestures
• receiving a second caution in the same match
Interpretation of the laws of the game and guidelines for referees
LAW 12 – FOULS AND MISCONDUCT
“Using excessive force” means that the player has far exceeded the necessary
use of force and is in danger of injuring his opponent.
• A player who uses excessive force must be sent off.
Serious foul play
A player is guilty of serious foul play if he uses excessive force or brutality
against an opponent when challenging for the ball when it is in play.
A tackle that endangers the safety of an opponent must be sanctioned as
serious foul play.
Any player who lunges at an opponent in challenging for the ball from the
front, from the side or from behind using one or both legs, with excessive force
and endangering the safety of an opponent is guilty of serious foul play.
Advantage should not be applied in situations involving serious foul play unless
there is a clear subsequent opportunity to score a goal. The referee shall send
off the player guilty of serious foul play when the ball is next out of play.
A player who is guilty of serious foul play should be sent off and play is
restarted with a direct free kick from the position where the offence occurred
(see Law 13 – Position of Free Kick) or a penalty kick (if the offence occurred
inside the offender’s penalty area).
