So much for cricket being a non-contact sport.
Usually you need to worry about getting hit in the head by the ball as a batsman or close-in fielder, but there are other dangers out there - like your fellow teammates.
The Brisbane Heat's Deandra Dottin and Laura Harris discovered that the most painful way imaginable, crashing into each other as they both attempted to field a ball near the boundary during their side's game against the Melbourne Stars at Brisbane's Allan Border Field on Tuesday.
The two converged as they tried to stop a ball hit out to mid-wicket from crossing the rope. They couldn't keep the Kookaburra in the field of play, and to make things worse, a sickening head clash saw both players tumble to the turf.
Dottin and Harris rolled around in obvious agony near the picket fence as players and staff came running to their aid. Harris was the first to recover it seemed, sitting up on her knees as a teammate and staffer examined her face.
