"Yes, I think it's minor. Maybe he was a little bit tired, but I think it's not a big issue," Pochettino told Spurs TV. "We will wait... the next few days to see what happened."
Tottenham midfielders Victor Wanyama and Erik Lamela also missed the Barcelona game.
"Erik (Lamela) was, after the game against Roma, a minor muscle injury, that's why he's here with us and we hope he can play against AC Milan," Pochettino added.
"Victor (Wanyama) has gone back with Tashan (Oakley-Boothe) to London to see the doctor. I think it was the same problem as last season in his knee. We will assess him in the next few days and see what happens."
Spurs play their final International Champions Cup match against Italy's AC Milan on Wednesday and face Girona in a friendly before their opening league fixture against Newcastle United on Aug. 11.
