Gul has suffered a succession of injuries since his debut in 2003
Fast bowler Umar Gul will miss the remainder of Pakistan's Asia Cup campaign because of injury.
Gul bowled only eight deliveries in Thursday's six-wicket Group B defeat by India before he was forced to leave the field in Karachi with a side strain.
"The doctors have advised Gul needs at least two weeks rest to recover from the injury," said Pakistan chief selector Salahuddin Ahmed.
"He will not be able to take further part in the Asia Cup."
Gul's absence is another blow to Pakistan's depleted fast pace bowling ranks.
They are already without Mohammad Asif, who was detained in Dubai for alleged drug offences, and Shoaib Akhtar, who is currently serving an 18-month suspension.
It is the latest in a long line of injuries suffered by Gul since he made his Pakistan debut in April 2003.
The 24-year-old spent a season sidelined with three stress fractures in his back in 2004 before an ankle injury kept him out of action in the latter stages of 2006.
