Key players on the Dallas Cowboys roster like receiver duo CeeDee Lamb and George Pickens as well as quarterback Dak Prescott participated in the joint practice the team held with the Los Angeles Rams during the week. However, it's unlikely that these players will take the field on Saturday for Dallas' first preseason game of the year."There's a handful of guys that won't play, but when you look at it, you have a target set of numbers that you want to get throughout the preseason. So maybe the number is 40 for a player," coach Brian Schottenheimer said on Friday."So maybe that's 10 to 15 plays tomorrow, another 25 or whatever against Baltimore, and then you decide the third game. Our players are aware of the kind of where they are going in this game."Schottenheimer did not mention specifically, but considering their significance to the Cowboys and their injuries from last season, Prescott and Lamb are probably going to be among those who will not play on Saturday.Meanwhile, Lamb told reporters Friday that he enjoys the preseason because it helps rookies get a sense of what to anticipate in the league."That's what this is for. I actually love the preseason just to kind of give them a spitting image of what we go through and putting themselves into the game," Lamb said.Since joining the Cowboys in 2020, Lamb has become one of the league's top receivers, with four consecutive trips to the Pro Bowl and one All-Pro First Team selection in 2023. As one of the most important pieces on the Cowboys roster, it's not a surprise that the team wants to prioritize his health by keeping him out of an exhibition game.Although he recorded 101 catches for 1,194 yards and six touchdowns last season, Lamb didn't give a level of performance fans have been accustomed to. That, however, was mostly because he missed two games because of injury and played without starting quarterback Dak Prescott for half of the season.How to watch the Cowboys vs. Rams preseason opener?The Dallas Cowboys will face the Los Angeles Rams in their preseason opener at SoFi Stadium on Saturday.
