Bangladesh added Farhad Reza and Taskin Ahmed to their squad for a tri-series in Ireland ahead of the World Cup.
Taskin will be cover for key bowler Rubel Hossain, who has been suffering from a side injury, and fast bowler Mustafizur Rahman, who is yet to recover from an ankle injury.
"We are concerned because the Bangladesh team is facing some injury problems, especially with their fast bowlers," Bangladesh Cricket Board chief Akram Khan said.
"The World Cup will be a long one, so we decided to take two more players for the Ireland series."
Bangladesh will take on hosts Ireland and the West Indies in the series from May 5-17, before heading to England for the World Cup which starts May 30.
Taskin was a standout in the Bangladesh Premier League in January before a ligament injury sidelined him. He was not considered ready when the World Cup squad was announced on April 16.
Bangladesh start their World Cup campaign against South Africa at The Oval on June 2.
