Gayle will miss tomorrow's away game against Mumbai Indians at the Wankhede Stadium here and also the next game against Rising Pune Supergiants in Pune on Friday. RCB face Gujarat Lions on Sunday in Rajkot.
Gayle's RCB teammate Sarfaraz Khan said it was still not known how many games he would miss.
"He has got a son. He's gone back (to Jamaica) to see him," said Sarfaraz at the pre-match media conference today. "It's uncertain how many games he will miss before rejoining the squad.
"Yes, all are available for selection. Kieron Pollard suffered from food poisoning in the last game. He did not make the trip to Hyderabad. He's here today and we will have full intensity practice session," Mumbai Indians coach Ricky Ponting said.
