Wright is resting an ankle injury and Adcock is sitting with a knee injury.
David Smoak of ESPN Radio in Central Texas tweeted on Sunday that Wright played through the ankle injury all season.
Considering he topped 1,600 yards and led the Big 12 in receiving, that's unreal.
Wright looks like a fringe first-round pick, but his stock will likely see the most movement during the week of the NFL combine next month.
Adcock is projected as somewhere around a third-round pick.
Here are the rest of the Big 12 players suiting up this week. Texas A&M defensive lineman Tony Jerod-Eddie was a late addition to the South roster. Practices and Saturday's game can be seen on NFL Network.
Texas A&M quarterback Ryan Tannehill (broken foot) was also named to the Senior Bowl team and will miss with an injury.
