The duo both went off injured during the Blues' 2-1 win over Aston Villa on Saturday but have traveled with the squad to AmsterdamJohn Terry and Eden Hazard will travel with the 25-man Chelsea squad to Amsterdam for Wednesday's Europa League final.
Both players suffered injuries during the Blues' 2-1 win at Aston Villa on Saturday with growing fears they would miss out on facing Benfica at the Amsterdam ArenA.
However, the pair joined John Obi Mikel, also returning after four matches with a hip problem, in the squad which will train at the Netherlands' national stadium on Tuesday evening.
A late fitness test should determine whether either of the three are fit enough to feature against Jorge Jesus' side.
Ryan Bertrand is also on the plane despite a recent knee injury and will be hoping for another cup final win after his involvement in Chelsea's Champions League triumph in Munich last year.
Oriol Romeu and Nathan Ake also traveled with the first-team squad to the Dutch capital but are unlikely to feature against Benfica.
Demba Ba will travel with the squad even though he is cup-tied having featured in the tournament this season for previous employers Newcastle.
