Gundogan, who is the Premier League champions' top scorer in all competitions this term with 17 goals this term, appeared to be suffering from discomfort in his right thigh after a collision with captain Fernandinho.
City's practice match at Estadio do Dragao continued in the Germany international's absence, with the players and manager Pep Guardiola retaining an overall relaxed demeanour – suggesting the nature of Gundogan's knock, being impact rather than muscular, meant it was not a major cause for concern.
Gundogan is the only member of the City squad to have featured in a Champions League final when he scored from the penalty spot in Borussia Dortmund's 2-1 defeat to Bayern Munich at Wembley in 2013.
The 30-year-old has been instrumental in City regaining the Premier League and retaining the EFL Cup this season, although he was an unused substitute for last weekend's 5-0 victory over Everton after being substituted following a blow to the knee in a 3-2 defeat at Brighton and Hove Albion.
"I'm alright, I was a little bit cautious in that Brighton game," he said when asked about his fitness earlier this week.
"Because of the knock on my knee I started to feel all the muscles around it a little bit and I didn't want to pull anything.
"I didn't miss any training sessions, so I'm feeling good."
All other members of Guardiola's first team squad trained, with no fitness concerns mentioned by the manager at his pre-match news conference.
