Georgia Southern Eagles quarterback Shai Werts (4) is tackled for a loss by Louisiana-Lafayette Ragin' Cajuns defensive back Tracy Walker (23) and defensive end Trev Miller (4) during the second half of an NCAA football game at Cajun Field on November 25, 2017 in Lafayette, LA.

INDIANAPOLIS — Louisiana-Lafayette safety Tracy Walker is going by another name this weekend at the NFL scouting combine, but not because he made the change on his own. 

Walker, who bears the same first name as both his father and his grandfather, arrived in Indianapolis to find out the NFL had written him down as Trey for the week.

"I get called by both," Walker said. "Tracy, preferably, but when I got here, they were calling me Trey, so I just stuck with it."

By whatever name, Walker has a chance to make an impression on NFL teams when he goes through his on-field workouts on Monday. A big, talented safety at 6-foot-2, 200 pounds who is projected to , Walker is only the sixth Ragin' Cajun since 2000 to participate in the combine, but Louisiana-Lafayette has now been represented at Lucas Oil Field two years in a row.

Running back Elijah McGuire participated last year, got picked up by the New York Jets in the sixth round and rushed for 315 yards as a rookie.

McGuire has given Walker tips on the draft process throughout this cycle. 

"That's my dog," Walker said. "Me and him are very close. We came in to ULL together, so we definitely go back. ... He told me it's going to be a little stressful, but he said it ain't nothing we aren't used to having."
