The concern is that Caicedo has been booked in five of his last six Premier League outings - including the last three in a row - so Maresca will need to have a word with his midfielder, perhaps advising him to watch his step with regards to tackling and dissent.
Under The FA's rules, players who receive a total of 10 yellow cards in their side's first 32 Premier League matches receive a two-match suspension.
Caicedo has been ever-present for Chelsea in the Premier League this season, starting all 27 matches thus far, but that record is under serious threat after being booked in the 4-0 win over Southampton on Tuesday night.
Caicedo being at risk of a suspension could hand Chelsea head coach Enzo Maresca a team selection dilemma going into next weekend's clash against former club Leicester City.
Though, Caicedo is the only Chelsea player in immediate danger as he needs to avoid a booking against Leicester, Arsenal, Tottenham, Brentford and Ipswich to escape a two-game ban.
