The Pittsburgh Steelers have released rookie cornerback Jaylon Guilbeau , the team announced on Friday, just days after signing him on Monday.
Guilbeau, 22, had two practices with the Steelers this week and participated in the team's preseason finale against the Buffalo Bills on Thursday. He played in 14 snaps, all on defense, 12 at outside cornerback and two in the slot. He had two tackles in the game.
Guilbeau was an undrafted free agent out of Texas this spring who originally signed with the Carolina Panthers . Guilbeau was released by the Panthers with a non-football injury designation on July 22. A 5-foot-11, 190-pound cornerback from Port Arthur, Texas, Guilbeau played both inside and outside cornerback for the Longhorns, though he likely projects as a slot cornerback at the NFL level.

He worked as a reserve his first two seasons, before becoming a starter in 2024 in the slot. He moved outside in 2025, and recorded his first career interception while breaking up three passes.
In pre-draft testing, Guilbeau showed solid explosiveness, with a 34.5-inch vertical, a 10-foot-5 broad jump and a 6.86-second three-cone drill, but just average long speed, with a 4.53-second 40-yard dash. He had an overall Relative Athletic Score of 6.95 out of 10.
The signing of Guilbeau came amid a rash of defensive back injuries for the team, which has largely subsided.
Guilbeau was one of 11 players released on Friday . The Steelers have until 6 p.m. on Sunday to complete their cut-down process, to get from 91 players to the league-mandated minimum of 53.
He will now go through waivers until 1 p.m. on Monday, when Guilbeau will be eligible to be added to the Steelers practice squad.
