Sergio Busquets will miss Barça's next game, on Wednesday against Rayo Vallecano, after being cautioned in the match against Atletico.
In the 57th minute, the Barça captain was shown a yellow for a tackle on Lemar: it is the fifth of his season, so he will not play in Vallecas, on Wednesday 26 April at 10pm.
In the action, Busquets pulled back Lemar, but curiously ended up with torn shorts himself, because Lemar also grabbed the Catalan player.
Busi has already missed the second matchday of La Liga, against Real Sociedad, due to suspension after being sent off in the first matchday against Rayo.
Busquets will be eligible to play for Barça again next weekend, when they face Real Betis at home.
