Minnesota Vikings star defensive end Jared Allen limped into the locker room with a sprained ankle Tuesday afternoon.
Allen had his left ankle taped and appeared to be in pain, according to the Minneapolis Star-Tribune.
Per the report, Allen hurt his ankle during a two-minute drill and couldn't return.
Vikings coach Leslie Frazier indicated that Allen will need more tests on the ankle to determine its severity.
"We'll look it over, and determine whether or not we need to do an MRI," Frazier said.
