"Jesse's incident was unfortunate. We really feel sad for it. His absence would mean additional responsibility. We have to rise to the occasion," the 20-year-old Delhi youngster said.
Ryder went into medically-induced coma after being attacked twice.
He is believed to have suffered serious head injuries after the assaults and has now been moved out of the intensive care as his condition was improving.
Chand, the former under-19 captain of the Indian team that won the World Cup last year, told media after practice here, "I have played well in Ranji matches this season. I have to maintain this form. I hope I would be able to retain the form I displayed in Ranji matches."
Asked to comment on the absence of Kevin pietersen and Ryder, Chand said, "Yes, they will be a big miss this time."
Asked whether he would be batting in one of those positions, Chand said, "The team management had not told him anything so far. I will bat in whatever position the team management will ask me.
