Daniel Flynn's return to action in New Zealand's first innings of the second Test is set to be delayed after he was hit on the head and had two teeth removed, team management said Saturday.
Flynn could come into bat at the fall of the first wicket on Saturday.
But he had to endure two hours of dental work Friday after, when on four, he was hit on the head by England fast bowler James Anderson at Old Trafford during the first day's play and had to retire hurt.
Although he was wearing a helmet, the ball appeared to force the grille into the 23-year-old left-hander's face after he missed a hook shot with his side then 136 for four.
A top front tooth was knocked out by the initial impact and a badly cracked bottom tooth was also removed Friday, team manager Lindsay Crocker said.
Initial indications were that Flynn, playing in only his second Test, would bat again but, after a night of nausea and vomiting saw the Northern Districts unable to eat, Crocker said he would not resume until he was fully fit.
"He's been quite nauseous and I think he's been vomiting, so in those circumstances we don't want him to go out there," Crocker said Saturday.
"Right from the start he wanted to go back out. It's the nature of the bloke, he's a very keen competitor and tough as old boots. But we're being sensible about it and he knows it's the right thing to do."
Crocker added Flynn had been booked in for dental reconstruction work at the end of the game but stressed concussion had been ruled out after Flynn was seen by a doctor when the team arrived at Old Trafford on Saturday.
"The longer the (first) innings carries on the more likely it is that he'll be able to take some part in this innings," Crocker added.
"If he doesn't there's still a long way to go and hopefully he'll participate in the match as it progresses."
Anderson, playing on his Lancashire home ground, said after Friday's close: "It's just one of those things. I'm trying to get him out and I want to make it as uncomfortable for him as possible. I've hit people on the head before but never had teeth to show for it."
