It's a rule that after amassing 5 yellow cards, you miss the next game then open another sheet for card accumulation. Bruno got yellow carded during the last Premier league game against Newcastle and will still be up against Chelsea. What happened... Follow me.
The rule clearly specify that there's a suspension for any player with 5 yellow cards amassed within a mid season, that is, 19 games whereas Bruno only had 4 yellow cards in the first half of the season and just got another yellow card that is, for this new midseason, he's been shown a yellow card once and will need four more yellow cards to be faced with a match suspension.
