Allen went down Saturday during a special teams period as the Chiefs practiced pooch punts. Chiefs special teams coordinator Dave Toub said Allen had been making a strong push for a role before the injury. "I hate to see somebody get hurt, especially on a special teams drill," Toub said. He's really doing well on offense, and he's doing well for me too. "Anytime you have a rookie, everybody is on special teams until they aren't, until they establish themselves, whether it's a starter on offense or defense," he said.
