Booker was the first to be injured, as he stayed on the ground after making a diving catch of a low Culpepper pass over the middle.
Booker, who was being covered by safety Travares Tillman, had both hands over his face while he was being examined.
Even though the injury and the circumstances surrounding it made it look worse, Coach Nick Saban said after practice the injury was a minor ankle sprain.
Saban said that Hill also sustained a minor ankle sprain.
The safety was injured during a running play where Travis Minor carried the ball.
A little before the injury, Culpepper surprised many observers by diving on a loose ball after an errant snap by Rex Hadnot in shotgun formation.
"How many times a day did I say, 'Stay off the ground, stay off the ground, stay off the ground'? Saban said. "We don't want receivers diving for balls, we don't want defensive backs going over the top and knocking them down trying to get a ball. Obviously, that's not going to ever be 100 percent. But we want players in competitive situations to especially play smart.
"Maybe it doesn't look as good, as play-wise. But we've got practice fast, practice smart and practice with the best safety of our players in mind."

-- Culpepper continued to look sharp in practice. He threw the ball well and also scrambled out of the pocket, as he did on Friday.
-- Vick saw action mostly at wide receiver and he showed very goods hands catching the ball.
-- Center Dominic Furio, claimed off waivers from Philadelphia a few weeks back, again was absent. Saban said Furio called offensive line coach Hudson Houck and was excused for personal reasons.
-- Center Wade Smith joined four other players wearing a red jersey after he "tweaked" a calf muscle. The others in red jerseys are LB Zach Thomas, FB Fred Beasley, DT Josh Shaw and CB Travis Daniels.
-- RB Kay-Jay Harris was back at practice Saturday morning after sitting out Friday afternoon.
-- CB Will Allen had the best defensive player of the morning practice as he intercepted a deep Culpepper pass intended for Booker in the end zone.
