James Anderson confirmed Stuart Broad was hampered by a foot injury on day one of the second Test between India and England, but was unable to divulge the severity of the issue.
Broad made a breakthrough in his first over on Thursday as England reduced India to 22-2. However, the 30-year-old could be seen limping later in the day as the hosts recovered impressively - through centuries from Cheteshwar Pujara (119) and skipper Virat Kohli (151 not out) - to close on 317-4.
Questioned on the fitness of his new-ball partner, Anderson told Sky Sports: "He's got a bit of a foot problem. He's been in the wars; he's got a bit of a graze as well on his arm, so he's nursing those at the moment in the dressing room.
"He did really well to get through the day, I thought. We don't know how serious his foot is, but he ran in really well and hopefully he can come back in the morning and be fresh for us."
Anderson was making his own comeback from injury in Visakhapatnam, having been sidelined since August with a stress fracture in his right shoulder.
Recalled in place of Chris Woakes, who emerged as a fitness doubt in the days leading up to the second Test, England's record wicket-taker reported no ill-effects after marking his comeback with three of England's four wickets.
"It feels alright - it might be a different story at seven o'clock tomorrow morning, but I feel good so far," added Anderson.
"I got through the day without any drama and hopefully I can have a good night's sleep and come back fresh tomorrow [Friday].
"I think it probably took me a little bit of time to get into the spells, a bit of stiffness as you go through the day, but once I got into the spells I felt fine."
