Controversies 
In 2017, after reports came to surface that Sumit had missed a practice session in July 2016 at Chandigarh during the tie against South Korea, citing elbow injury. He was dropped from the Indian Davis Cup squad led by Anand Amritraj which was scheduled to face the New Zealand between 3 and 5 February 2017. A source close to All India Tennis Association (AITA) told Sportskeeda, "It is a case of sheer indiscipline, on the part of the player. He missed several training sessions, brought his girlfriend to the camp without informing us. Several other discrepancies have also emerged, which led to the captain taking this call." Nagal denied the allegations, he got support from former India player Somdev Devvarman who stated that "I want to be clear once again. You have not chosen Sumit Nagal for the upcoming tie, because Sumit Nagal is NOT available to play. How do I know this? Because I have spent 2 weeks with Sumit in December helping him with his training and his rehab for the current shoulder injury he is recovering from."
