This is a tough break.

Childs slid in the draft because of injuries at Arkansas and now he suffers another devastating injury before even playing a down in the NFL.

Minnesota Vikings rookie receiver Greg Childs suffered patella tendon tears in both knees and is expected to undergo surgery soon, the team announced Sunday.

Childs, drafted in the fourth round of the 2012 draft, was injured Saturday night after he jumped to catch a ball thrown slightly behind him. The ball bounced away and Childs landed awkwardly.
