You're not watching the same video I'm watching. The first contact was Tejada's left leg going up Utley's chest and then striking Utley in the face. After Tejada's knee hits Utley's face, Utley then slams into Tejada's right leg (which is the one that was broken) with his crotch and Tejada's left foot then gets swept out from underneath him. The proof on this sequence is that Utley's helmet gets knocked off well before he hits Tejada's right leg which is the leg furthest from Utley.
Meant to say Tejada’s right leg gets swept out from underneath him - not the left leg.
