The Metairie (La.) Archbishop Rummel High three-star defensive tackle chose Arkansas over offers from schools such as Alabama, LSU, Mississippi State, Ole Missl, Penn State, Tennessee and Texas A&M.
"I thought I'd commit during the summer, but I just thought it was time (Saturday)," Guidry said. "It feels great and I'm excited."
Guidry was originally committed to Mississippi State, but de-committed in December 2014. By committing to Arkansas, he is the Razorbacks’ first out-of-state pledge for 2016.
He said that he was drawn to Arkansas because of the opportunity to get on the field early in his career, but he also likes Fayetteville, which he has visited twice - for last year's spring game and for one of the games during the season.
"It's a nice area," Guidry said. "They have a great fan base and the coaching staff knows what its doing."
Another reason Guidry chose the Razorbacks is because of their defensive turnaround in 2014 under defensive coordinator Robb Smith. Head coach Bret Bielema's reputation for producing NFL-talent on the offensive and defensive lines was a factor, as well.
"I called the coaches (Saturday) evening," Guidry said. "They can't wait."
Following his junior season, Guidry was named to The Times-Picayune Large Schools All-Metro team.
The Razorbacks now have four commitments for their 2016 class. Guidry joins four-star defensive tackle Austin Capps (Star City, Ark.), three-star wide receiver Jordan Jones (Smackover, Ark.) and three-star athlete T.J. Hammonds (Little Rock Pulaski Robinson).
