Alastair Cook has said England will make a late call on their team for the second Test against India, as the tourists weigh up the fitness of Chris Woakes and James Anderson.
Speaking at his pre-match news conference in Visakhapatnam, Cook confirmed Woakes had been hampered by a "bowling niggle", placing his selection in doubt.
The seam-bowling all-rounder could be replaced by Anderson, England's record wicket-taker having come back into contention following a shoulder injury.
However, a recall for the 34-year-old would not be without risk given he has not played a match since August, so Steven Finn or Jake Ball could yet be pressed into action if Woakes is rested.
Asked whether England would name an unchanged side after impressing in last week's drawn series-opener, Cook said: "I can't quite answer that just yet.
"It's a real tough one. We know what we've got [coming up in terms of a hectic schedule] but the way the 11 guys played in the last game was outstanding. So it's the old rotation policy or do you stick with what we've got? That's the decision we've got to make.
"He [Woakes] is the one we're looking at because of the amount of overs he has bowled over the last six weeks. He bowled outstandingly well in the last Test. He has just got a bowling niggle really ... just the normal wear and tear of bowling, so he's fine to play."
Discussing a potential recall for Anderson, Cook added: "It's the question we have to ask ourselves. He's come over and bowled well in the nets and he's confident.
"He hasn't got miles in his legs though and you are weighing that up against seamers who have been with us all winter and Woakes as well.
"Hindsight on this one will be easy in five days' time. But at the moment it is still going through our heads what to do."
