The rapper has been in training since last year when he was expected to fight fellow rapper AKA.
Although his match with rival AKA is still in the balance Cass is currently preparing to face his other rival Prince Kaybee.
Cassper who has been posting a series of videos of himself training for the match against Prince Kaybee shared on twitter that during his sparring session he injured himself.
“Got hurt sparring today. Boxing is not play-play. Now and then you’ll get a harsh reminder.
“Wonder how long it’ll take to recover so I can get back while we wait for that clown ro step up to the challenge. Loud mouth with no action. Phone full of memes, empty heart,” said Cassper.
