Goalkeeper Edouard Mendy took part in Chelsea's training session as he geared up to be ready for the Champions League final against Manchester City on Saturday.
Thomas Tuchel's trusted custodian hurt his ribs after colliding with a post during the final game of the season against Aston Villa on Sunday and did not come out for the second half.
Earlier in the week, manager Tuchel expected Mendy to be available for the title showdown in Lisbon.
"He has made huge improvement in the management of pain," Tuchel had said.
"He will play if he is fit. We will try on Wednesday, if not then we will try on Thursday, if not then we will try on Friday. If he cannot make it then we have a strong guy on the bench with Kepa. The images don't show that the injury is too serious."
As it turned out, Mendy began training alongside midfielder N'Golo Kante, who had been taken off in the match against Leicester with a hamstring niggle.
Both players will be desperate to be fit in time as the the Blues face Premier League champions City at the Estadio do Dragao.
The two teams have already met three times this season with Chelsea victorious on two occasions.
Hakim Ziyech secured a 1-0 FA Cup semi-final win, while Ziyech and Marcos Alonso clinched a 2-1 league victory at the Etihad Stadium. City had started the year with a 3-1 win in January.
