Wales prop Henry Thomas has been ruled out of the international against world champions South Africa on Saturday at Twickenham because of a foot injury.

There are further front-row injury concerns with Dragons hooker Elliot Dee set to miss the trip to Australia after finishing the season with an ankle injury.

Scarlets hooker Ryan Elias has been rested for the summer programme with Dewi Lake, Evan Lloyd and Sam Parry the other specialists named in the official extended training squad.

Cardiff hooker Efan Daniel has been called into train with Wales and is now in contention to travel to Australia alongside Lake and Lloyd.

Daniel, 21, is set to be a travelling reserve at Twickenham alongside Ospreys tight-head Ben Warren, who is also covering concerns about the fitness of Harlequins prop Lewis.

Meanwhile, Gatland has called up Bath wing and rugby league convert Regan Grace to his wider squad after Keelan Giles was ruled out by injury.
