The Arsenal defender joined his Scotland team-mates for training 24 hours after missing their Euro 2020 opener.
Tierney was filmed warming up alongside other players who did not start in Monday’s 2-0 Hampden defeat to the Czech Republic.
Scotland head coach Steve Clarke revealed on Monday that Tierney had picked up a “little niggle” in training but was hopeful the former Celtic player would return for Friday’s second group game against England at Wembley.
Speaking on Tuesday afternoon, Clarke said: “He did a little bit of light training and we will just see how he progresses. He’s got a chance.”
