England hooker Jamie George has been called up to the British and Irish Lions squad after Luke Cowan-Dickie emerged as an injury doubt for the first Test against Australia next Saturday.
Hooker Cowan-Dickie, 32, looks likely to miss the game in Brisbane after suffering a suspected concussion in Saturday's big win against the AUNZ Invitational XV.
The England forward left the field on a stretcher with his head in a supportive brace after being injured while tackling Lukhan Salakaia-Loto.
"He got up straight away as he got off the stretcher and he's back to being his normal self," said Lions head coach Andy Farrell.
"It's unfortunate for him, so we'll see what has to happen on the back of that."
Ireland and Leinster tight-head prop Tom Clarkson will also join the squad to provide additional front row cover.
Both of Ireland's regular tight-head props Tadhg Furlong and Finlay Bealham are already in Australia, with Clarkson linking up after starting Ireland's 106-7 win over Portugal on Saturday.
George, a two-time Lions tourist, is in Argentina and was set to co-captain England in their second Test, but will instead join up with the Lions in Brisbane next week.
He also trained with the Lions in Dublin before the squad departed for Australia.
"We're absolutely delighted for Jamie's selection," said England head coach Steve Borthwick.
"This is also a fantastic opportunity for Theo and Curtis, who have both worked incredibly hard and really impressed in training."
