The official line from Indian team management is that Binny has just been added as the 16th member of the squad but he is not replacing anyone in the current squad.
The BCCI media release states, "All-rounder Stuart Binny will join the Indian Cricket Team before the second match of the three-match Test series in Sri Lanka."

It has been learnt that Murali Vijay's hamstring injury is being monitored by Team physio Patrick Farhart and a final call on his inclusion in playing XI will be taken a day before the second Test.
