The Cowboys and Texans are kicking off the preseason. Dallas takes on the Broncos tomorrow night in Denver. The Cowboys held a joint practice with the Broncos on Thursday with Dak Prescott and CeeDee Lamb connected on a touchdown during the practice. Meanwhile, Houston won't be acquiring tight end Adam Shaheen after he failed his physical to void the trade. Houston retains its 2023 sixth-round pick as a result. The Texans open the preseason tomorrow night against the Saints at home.
