TUSCALOOSA -- Alabama opened preseason practice Friday morning with its first of two sessions on the day. The Crimson Tide’s veterans and a few new faces took the field for the early workout while the rest of the newcomers are expected to practice for the first time later tonight.

Here are some takeaways:

--Sophomore cornerback Eddie Jackson (knee) was seen working with his position group wearing a brace on his right knee. Jackson injured his knee in a non-contact situation during spring practice. While it’s still early, Jackson’s rehab appears to be going well.

--Quarterback Jacob Coker was one of three quarterbacks in the early session, along with Blake Sims and Cooper Bateman. Coker worked behind Sims and Bateman, running drills with sophomore running back Kenyan Drake.

--Freshman punter JK Scott worked with the veteran group.

--Wide receiver DeAndrew White (toe) and defensive lineman Darren Lake (pectoral) both worked with their position groups and showed no signs of injury.

--Redshirt sophomore Chris Black has a new number. Black wore No. 1 during practice after sporting No. 5 last season.

--Despite being listed as a linebacker, D.J. Pettway continued to work with the defensive linemen.

--Pettway, Lake, Dalvin Tomlinson, A’Shawn Robinson, Jonathan Allen and Anthony Orr were the defensive linemen in the first session.

--T.J. Yeldon, Derrick Henry, Drake and Jalston Fowler were the running backs during the first session.

--It’s way too early to get a feel for who’ll be starting, but the first offensive line group through drills featured Cam Robinson at left tackle, Arie Kouandjio at left guard, Ryan Kelly at center, Alphonse Taylor at right guard and Austin Shepherd at right tackle.

--Dominick Jackson is a newcomer, but he was seen working at right guard during the first session.
