New Zealand spinner Daniel Vettori could play his first Test in 10 months against England at Headingley.
His fellow left-arm spinner Bruce Martin has been ruled out of the tour with a calf strain.
Veteran Vettori was originally picked in the ODI squad and has not played a first-class game since suffering an Achilles injury in July last year.
He has been in India with IPL side Bangalore - though he did not play a game - and has flown out a day early to ensure he is ready for the second Test.
Coach Mike Hesson said: "Daniel's come over 24 hours earlier for us to have a chance to have a look at him. We won't be pushing Dan if he's not ready but if he is we'd certainly love to have him.
"He's done plenty of bowling in the last couple of months in the IPL, albeit in the nets. He's got through plenty of work.
"But it's a matter of whether we think he's going to be able to get through five days of a Test match. We won't risk Dan for the sake of a test. But in saying that it is an important Test match for us.
"Dan loves playing for New Zealand but he's also realistic. We'll make a thorough assessment and we won't push it."
There was some good news for the Kiwis on keeper BJ Watling. He suffered a badly bruised knee in the first Test at Lord's and had to be replaced behind the stumps by skipper Brendon McCullum.
But Hesson said: "We're hopeful if he continues that he'll be a good chance for the second Test."
