A shortage of centre-backs could see Daniele De Rossi used in defence for Roma against Juventus next Monday evening.
The Giallorossi will be without the injured Nicolas Burdisso and Simon Kjaer, while Juan will be suspended after his dismissal at Fiorentina on Sunday.
Enrique now only has one recognised centre-back in his squad – former Manchester United and Real Madrid man Gabriel Heinze.
The Spanish tactician, under fire after another defeat, could use right-back Marco Cassetti in the middle or opt for De Rossi.
To complicate matters, De Rossi’s natural replacement in midfield, Fernando Gago, is also unavailable after he too was red-carded in Florence.
