OXNARD, Calif. -- The Cowboys didn't have helmets or shoulder pads during Monday's walkthrough practice. Tuesday is a two-a-day.

Here are the highlights:

*Before practice, Miles Austin and Dez Bryant were working out with wide receivers coach Ray Sherman. Bryant also had a little chat with Cowboys owner Jerry Jones.

*Scott Sicko, Alex Barron, Martin Rucker and Mike Hamlin returned to practice. Rucker is a newly signed tight end who was fighting a hamstring problem.

*Kyle Kosier (knee), Marc Colombo (knee), John Phillips (knee), Gerald Sensabaugh (shoulder), Keith Brooking (shoulder), Stephen Hodge (knee) and Marcus Spears (knee) missed practice. Phillips said he might undergo ACL surgery when the team breaks came on August 27.

*Former MMA star Chuck Liddell talked to the team before practice, and when it was over guard Montrae Holland broke the team out with the Florida State Seminole chant.

*Hamlin got first-team reps at safety with Sensabaugh out. Sean Lee was on the first-team at inside linebacker in place of Brooking.

*Barron and Robert Brewster practiced at right tackle with the first team. Brewster got more reps with the first team than Barron. Brewster also got left tackle reps with the second team. Sam Young received second-team reps at right tackle.

*Martellus Bennett continued to run smoothly during practice despite a sprained ankle. Bennett is cutting on that left ankle and is making few mental mistakes, if any.

*Offensive coordinator Jason Garrett got on Austin for a mental mistake. Austin was supposed to run an out route; instead he ran a curl.

*The Cowboys showed a formation where Austin is in the backfield and Tony Romo fakes a pitch to him and then fires a pass to Roy Williams in the back of the end zone. The first time the Cowboys ran the play against the defense, Williams wasn't open. Romo still threw the pass into coverage and Williams caught it.
