Craig Bellamy and John Arne Riise were both part of the Liverpool squad which jetted out to Spain today to prepare for tomorrow night's Champions League against Barcelona at the Nou Camp.
The pair were reportedly involved in a training-camp fracas and could face punishment once boss Rafael Benitez has got to the bottom of the incident.
Welsh star Bellamy is set to start against the Spaniards while Xabi Alonso should also be available again after missing the Barclays Premiership defeat at Newcastle through suspension.
Provisional squad: Reina, Finnan, Agger, Hyypia, Carragher, Riise, Aurelio, Pennant, Gerrard, Sissoko, Alonso, Zenden, Bellamy, Crouch, Kuyt, Fowler, Gonzalez, Arbeloa, Dudek.
