Gachkar (thumb) is back with the team following thumb surgery, Rob Phillips of Dallas Cowboys.com reports.
The 27-year-old line backer had surgery done on his thumb Friday, and is currently without a timetable of return. Head coach Jason Garret indicated he will be out "a little while". He is currently doing conditioning work with the team.
Elliott (hamstring) is slated to receive up to a dozen snaps in Thursday's preseason contest in Seattle, Brandon George of the Dallas Morning News reports.
Elliott's first game action as a Cowboy is coming on the heels of three consecutive full practices. Of particular interest will be his usage, as reps on third down would substantiate the belief that he'll serve as a bell-cow back. In the end, though, emerging from the contest unscathed is the team's primary goal at this point.
Moore, who suffered a broken left ankle Tuesday, is expected to miss three to four months, NFL.com reports.
Moore is slated to undergo surgery Wednesday to address the issue, which for the moment leaves Dak Prescott and Jameill Showers -- a pair of inexperienced signal-callers -- as the team's backup options behind starting QB Tony Romo.
Escobar (Achilles) did not practice on Sunday, Todd Archer of ESPN.com reports.
Escobar will get the day off as he continues to nurse a torn Achilles he suffered last season. If he continues to miss practice time he may be in danger of missing the Cowboys' first preseason matchup against the Rams next Saturday.
McFadden (elbow) has no timetable for a return to practice, Jon Machota of the Dallas Morning News reports. "I'm just working, strengthening it and getting everything back together," McFadden said Sunday.
Although a recent bone scan yielded positive results, a broken elbow is not to be trifled with. As a result, rest and rehabilitation will dominate McFadden's upcoming schedule, with an unfortunate consequence that he won't be able to stake a claim to the top backup running back job to Ezekiel Elliott. As long as McFadden is sidelined, free-agent pickup Alfred Morris is the favorite to hold down the fort behind Elliott.
Wilson (eye) was activated off of the Cowboys' NFI list and participated in Monday's practice, the Fort Worth Star-Telegram reports
Dallas' fourth-round pick in the 2015 NFL Draft, Wilson was hit in the eye while playing paintball in late July, but no long-term impairments are expected to manifest. Nonetheless, Wilson earned glowing reports from the Cowboys' coaching staff throughout the team's offseason program and appears headed for a backup role in 2016 behind the likes of Sean Lee and Kyle Wilber.
Smith (knee) was placed on the PUP list Friday, Brandon George of the Dallas Morning News reports.
Smith continues to deal with nerve damage to his left knee, which was an unfortunate side effect of tearing his ACL and MCL in the Fiesta Bowl with Notre Dame on Jan. 1. However, the nature of the injury didn't stop the Cowboys from using a second-round pick on the linebacker during the 2016 NFL Draft. Afterward, executive vice president Stephen Jones acknowledged that he may not play this season, but owner/GM Jerry Jones later wouldn't shut the door on Smith achieving active status late in the season or during the playoffs, if the Cowboys were to earn a berth. In any case, Smith is likely destined for the IR/designated-to-return list to start the season due to his boss' perceived hope.
Lawrence's four-game suspension for violating the NFL's substance abuse policy has been upheld, Todd Archer of ESPN reports.
Lawrence received the four-game suspension back in April and filed an appeal in May. Now that the suspension has been upheld it's clear that Dallas will be without Lawrence, Randy Gregory (suspension), and Rolando McClain (suspension) to start the year, three significant players on the team's front seven. With Lawrence out, Ryan Russell, David Irving, and Benson Mayowa figure to see some extra snaps to start the year.
Jackson was a frequent and productive target of Jameis Winston in Thursday's joint practice with the Jags, of the team's official site reports.
The veteran had his day in the sun during Thursday's session, making plays up and down the practice field. Jackson hauled in a pair of deep passes from Winston during the session and was also targeted frequently during team and seven-on-seven drills. Although he hasn't necessarily drawn any headlines during camp so far, Jackson's veteran savvy and steady presence remains an integral component of the Bucs' wide receiver corps, and offense as a whole, heading into the 2016 campaign.
Sims (ankle) gained 20 yards on five carries in Saturday's preseason game against the Jaguars.
Fully recovered from a minor ankle injury, Sims got the start in place of Doug Martin (bruised ribs), who is also a bit banged up. The result was an unusual stat line, with Sims getting five carries and zero targets. No matter, the two running backs figure to reprise their roles from last season, with Martin getting most of the carries and Sims handling passing downs.
