Carter, a native of Mansfield, Texas, recently completed his redshirt senior season with the Razorbacks. He finished with 25 tackles, including 3.5 for lost yardage, and 1.5 sacks in 2023.
Carter posted a season-best five tackles in Arkansas’ home loss to Auburn on Nov. 11.
Following a 24-tackle season in 2021, the lineman was among the standouts in the Razorbacks’ spring drills in 2022. He then tore his ACL in the team’s spring showcase and missed the 2022 season.
According to Pro Football Focus, Carter played 261 defensive snaps in 2023 and posted an overall defense grade of 56.6 and a tackling grade of 72.4.
Manuel, who just completed his redshirt sophomore season, battled injuries during the 2023 season but played in nine games. He played 417 offensive snaps, according to PFF, the eighth most on that side of the ball.
PFF data also shows he had an overall offense grade of 68.4.
The Sunset, La., native was considered a 3-star prospect out of high school by 247 Sports, Rivals and ESPN, and the No. 78 overall offensive tackle in his class.
Manuel initially chose Arkansas over offers from Iowa State, Michigan State, Houston, Indiana and other programs.
Carter is at least the fifth Razorback defender to announce plans to enter the NCAA transfer portal in the last couple of weeks. Manuel is at least the third offensive player who intends to transfer.
