Saini walked off the field during the 18th over of CSK’s innings on Sunday.
The incident happened during the 18th over of CSK’s innings as Saini picked up an injury on his right thumb and walked off the field.
RCB said that he is not sure when the fast bowler will be good to go.
"Saini has split his webbing in the last ball there. He obviously got hit on the thumb on the right hand. He has just split the webbing over there, fortunately, we had a good hand surgeon, he stitched up nicely. So we could just monitor over the night and check it after getting ready for the next game," Speechly said after the match, as quoted by ANI.
"Virat four-five years ago he had it in Kolkata, we managed to stop the bleeding and he smashed a 100 after we got a plastic surgeon who had stitched it," he continued.
"Unfortunately you cannot compare the two injuries. Some people can manage it and some can't. Its also because Saini's injury is on his bowling hand so it puts a lot of pressure on him so I cannot be sure when he will be good to go, I am hoping that he will be good to play in the next game and the rest of the tournament," he further said.
Coming to the match, RCB suffered an eight-wicket defeat at the hands of CSK in a low-scoring affair.
Opting to bat first, the Bangalore-based franchise posted 145/6 in 20 overs. Captain Virat Kohli was the top-scorer with 43-ball 50.
In reply, CSK rode on Ruturaj Gaikwad’s 65 not out off 51 balls to overhaul the target with 8 balls to spare.
Despite the loss, RCB are well and truly on their way to the playoffs with 14 points from 11 games and need only one win to officially clinch a berth.
