A police spokesman told VOA security forces were also among the victims.
Afghanistan Cricket Board officials confirmed all the players were safe and reported no casualties inside the Kabul stadium.
The blast forced teams to stop the match of the Shpageeza Cricket League but it has now been resumed, officials said.
There were no immediate claims of responsibility.
The two week long cricket tournament kicked off Monday at the Kabul stadium at a time when the capital city has seen repeated attacks in recent months claimed by the Taliban and Islamic State affiliates.
