India cricketer Dinesh Karthik couldn't stop himself from taking a jibe at Rohit Sharma's bowling. India's vice-captain Rohit was asked to bowl on the opening day of the ongoing fourth Test against Australia after Navdeep Saini got injured.

Saini picked up an injury during his 8th over in the match. It happened on the second last ball of the over. He managed to get an outside edge of Marnus Labuschagne but the catch was dropped by captain Ajinkya Rahane. 

Both Saini and the ball were on the ground and it didn't look like a good sight for the Indian team. He had to walk out in pain and Rohit completed the over by bowling the last ball.

Karthik was following the match and he jokingly tweeted that Rohit's medium-fast delivery was a lesson for the likes of Jasprit Bumrah and Mohammad Shami.

"@Jaspritbumrah93 and @MdShami11 better watch out, the new fast bowler in the wings @ImRo45 #absolutelyrapid," Karthik wrote on Twitter.

Rohit usually bowls off-spin and also has a hat-trick in IPL while playing for Deccan Chargers in 2009.
