X-rays taken Saturday night at the Georgia Dome were negative, and White said doctors told him he would miss two or three days of practice.
Many players often require three to five weeks before they return to action. Though Roddy White remained third on the depth chart behind Dez White and Brian Finneran, Mora wants a No. 1 receiver to emerge now.
"I watch our practices, I watch the way those guys compete and interact and I'm happy with where they are," Mora said. "We're looking for a breakout. We're looking for someone to grab it and say it's mine."
A two-hour practice begins at 3 p.m. today. Camp officially ends on Thursday. The Falcons play their second and last home preseason game the following night against Tennessee.
