And who might his No. 1 receiver be? Here's a look at the Cowboys' uncertain wide receiver depth chart before their Thursday afternoon clash with the Raiders.MORE: The Cowboys have one of the best receiving corps' in the NFL when they're healthy. Even with Amari Cooper and CeeDee Lamb out against the Raiders, their depth is solid. Things would have been better had Lamb been able to play, but they still have four receivers who have proven to be quality players during their NFL careers.1. Michael GallupGallup has been a bit of a forgotten man in this Cowboys offense, as he has mi sed roughly half of Dallas' season and has appeared in just three games to date. The fourth-year pa s-catcher saw season highs in catches (5), targets (10) and receiving yards (44) last week against the Chiefs with Cooper (COVID) out and Lamb (concu sion protocol) exiting the game early.During his career Russell Martin Jersey , Gallup has averaged 15.2 yards per catch and had 1,107 receiving yards in 2019. The 6-1 receiver is a good downfield threat and will see plenty of targets as the No. 1 receiver with Cooper and Lamb out of action. Of course, he may also face coverage from the Raiders' No. 1 corner, Casey Hayward, so that's worth keeping in mind.INJURY UPDATE: 2. Cedrick WilsonThe Cowboys were OK in the absence of Gallup because Wilson performed well in his stead. Wilson has played in 10 games and has racked up 316 receiving yards and three touchdowns on 23 catches. He has been the No. 3 receiver and hasn't always seen a lot of targets he has seen 34, good for sixth-most on the team but he has brokensome big plays.Wilson has also thrown the occasional Kenta Maeda Jersey pa s this season, and he has completed both of his attempts for 57 yards. Dallas will certainly look to get the ball in his hands at least a few times. He is averaging 13.7 yards per reception, which is second-most on the team to only Lamb among players with 10 or more receptions this season.3. Noah BrownBrown has emerged as a quality depth player for the Cowboys this year. He has caught just eight pa ses this season but has generated 117 yards. The 6-2, 225-pound receiver is a well-rounded backup who is both physical but can also serve as a down-the-field threat.Brownhas played 28 percent of the offensive Sandy Koufax Jersey snaps this year and has served as the No. 4 receiver for most of the seasonbecause of Gallup's injury. He'll be the No. 3 receiver this week and may see closer to 50 percent of the snaps depending on Dallas' game plan at receiver.MORE: 4. Malik TurnerTurner caught five of seven targets for 35 yards and two touchdowns in the Cowboys' lo s to the Broncos. His production came largely in garbage time, but he represents another big-bodied receiver that can catch make contested catches and will be bigger than most defensive backs Corey Seager Jersey .Turner will be the No. 4 receiver on Thanksgiving. He could play a quarter to a third of the snaps like Brown has most of the year as the No. 4 receiver.5. Simi FehokoFehoko has played just four snaps on offense this season. He hasn't yet been targeted and hasn't been active since Week 3. He will dre s with Lamb out, but the fifth-round rookie will only be an emergency depth option at receiver, in all likelihood.
