Rahman was hit on the head by a shot by Litton Das in adjoining net.
The incident happened during nets at the Zahur Ahmed Chowdhury Stadium. The incident took place on Sunday morning while Comilla were preparing for their next BPL game against Sylhet Strikers on Monday.
Rahman was hit on the left side of his head and eyewitness reported that Mustafizur was near his bowling mark when he got hit by the ball. Team-mates and coaching staff rushed to his side and took him to the ambulance at the ground after the pacer began bleeding from his head.
"During practice, a ball hit directly at the left parietal area (head) of Mustafizur Rahman. There was an open wound at his parietal area and we have worked with compression bandage to stop bleeding and immediately shifted him to Imperial hospital," a media release issued by team physio SM Zahidul Islam Sazal stated.
"After CT scan we are satisfied that he's had only an external injury. There was no Intra-Cranial bleeding. Now surgical team has given him stitches to treat the open wound. Now he is under close supervision of Comilla Victorians team physio,” he added.
Comilla's media manager Sohanuzzaman Khan revealed that the pacer was in good spirits.
"When we were prepping him for the ride to the hospital, he seemed to be acting normally," he said.
