Jalen Carter dealt with cramping muscles and heavily breathing that caused him to not finish his position drills on Wednesday at Georgia’s Pro Day.

He also weighed in 9 pounds heavier than at the NFL Combine, as ESPN’s Mark Schlabach reported that the defensive lineman weighed 323 pounds. Carter worked out in front of scouts and coaches from all 32 NFL teams in Georgia’s indoor facility. Three head coaches — the Falcons’ Arthur Smith, Bears’ Matt Eberflus and Steelers’ Mike Tomlin — were in attendance.

He opted to do only position drills and didn’t participate in other aspects of the workout, including the 40-yard dash, cone drills and other physical tests.

This appears to be another hit to Carter’s draft stock as he was once thought to be in the mix to be the No. 1 overall pick.  Carter was arrested for his alleged role in a Jan. 15 car wreck in Athens that killed Georgia offensive lineman Devin Willock and recruiting staffer Chandler LeCroy.

Georgia coach Kirby Smart was at the Pro Day, and told Schlabach about Carter’s performance on the field.

“I can speak to the competitive character of the young man,” Smart told ESPN. “I got to see it every day in practice and every day in games. It shows tremendous committed character to have two injuries that you could have quit playing [but came back]. He could have sat out the rest of the year.

“He wanted to come back. He wanted to win football games. One of the greatest traits Jalen has is his teammates, his brothers. He endears himself to his teammates and wanted to come back for those guys.”
