However, Gatland hinted Tipuric may not be able to follow up his Lions success in South Africa this summer as a shoulder operation remains a possibility for the openside flanker.
Gatland said: "Justin has a shoulder problem which might need some work doing at the end of the season.
"It could need an operation, a shaving of some bone, and there's a possibility he could be ruled out of the tour by it.
"But we've got other options because I think South Africa is a team you can play against, because of the size of the players they pick in their back-row, without a specialist openside."
Wales will certainly be without the services of Lions captain Sam Warburton, who dislocated his shoulder in March against Scotland.
