Before the tournament started Celtic tweeted good luck to five players with the defender missing from that tweet.
There has been a lot of confusion and speculation over Hendry making his loan move to Oostende permanent but there has been no comment from either club.
It seemed quite a climbdown after being included in the opening match against the Czech Republic with Clarke putting Declan Gallagher, Liam Cooper and Scott McKenna on the bench ahead of Hendry.
After appearing to be out in the cold at Celtic Hendry had an outstanding season on loan at Oostende with claims that a number of English clubs wanted to sign him on a permanent basis.
