Kyle Walker missed Manchester City training with a back problem on Tuesday afternoon ahead of the Champions League final.
After claiming the FA Cup with victory over Manchester United on Saturday, City are on the cusp of clinching an historic treble, with Inter Milan standing in their way in Saturday's Champions League final in Istanbul.
Addressing Walker's absence from training, Pep Guardiola said: "He had a disturbance in his back. Yesterday he was not good. Today he was a little bit better. We didn't want to take a risk and we will see in the next days."
After finding himself behind Manuel Akanji in the pecking order throughout March and April, Walker forced his way back into the side in the final few weeks of the season.

He played the full 90 minutes in eight of City's last nine Premier League games as well as both semi-final legs against Real Madrid and the FA Cup final so losing him would be a blow.
The right-back conducted media duties at City's training ground while not on the grass which could be an encouraging sign that he will be involved on Saturday.
Though Walker was missing, the rest of the players took part in the session and there was even a special guest in attendance at the City Football Academy as Arsenal legend Thierry Henry visited the session. He had a conversation with Guardiola and greeted the players as they left the field.
