"As far as I know, in our team, no one has done that. I can't really answer that question," Singh said.
Despite carrying injury, Kolkata Knight Riders skipper Gambhir played the eliminator against Mumbai Indians on May 25 and the move has now snowballed into a major controversy, sparking a debate on whether players are more keen to play in cash-rich events like IPL rather than the country.
Singh said the outcome of tomorrow's must-win second qualifier match against Royal Challengers Bangalore will depend on how his boys execute the plans.
"Obviously, we have thought about how we want to go about things. We have our own plans ready for what we would like to do. The important thing is to be able to execute those plans.
"It's obviously a knockout game. We have done pretty well against RCB. The few outings we have had in the past, we have beaten them. This is a fresh game. We have to start from scratch. We have to refocus and regroup," Singh told reporters here today.
The former India left-hander is also aware of the threat Chris Gayle poses.
"You can't ignore the fact that Gayle is in terrific form, and similarly with most of our bowlers, we have been bowling exceptionally well. You have to back yourself to bowl well against anyone." .
