Elqutub, a 6-1, 235-pounder, reported to the Lions over the weekend after being signed to the practice roster. The team's second regular-season game of 18 total is July 4 against Toronto.
Elqutub, from Houston and Cinco Ranch High School, had 50 tackles as a senior, including 29 solo stops, including three tackles for lost yards. He broke up three passes and had eight quarterback hurries.
A two-year starter who was honorable mention All-Southland Conference as a junior, he finished with 121 career stops in three seasons.
As a Demon, Elqutub had a bevy of honors, including on-field recognition at the 2012 Allstate Sugar Bowl in New Orleans as captain of the Allstate AFCA Good Works Team.
He was one of 22 seniors from all levels of college football chosen for the Good Works Team, then was elected by fan vote on ESPN.com as the team captain.
He also was selected one of 16 National Football Foundation Scholar-Athletes, earning an $18,000 postgraduate scholarship.
He was the only college football player to win both awards in 2011.
The linebacker, a second-team 2011 Academic All-America selection, was a two-time Academic All-Southland Conference pick.
He was presented an Nth Degree at his graduation by university president Dr. Randy Webb while he graduated magna cum laude.
The award is given in recognition of unselfish devotion to duty and the willingness to go the "extra mile" in meritorious service to mankind, and it had never before been given at commencement to a graduating senior.
Elqutub was president of both the NSU and Southland Student-Athlete Advisory Committees.
He won the Southland's 2010-11 Steve McCarty Citizenship Award. He posted a 3.85 grade point average in scientific inquiry at the Louisiana Scholars College at NSU.
He had foot surgery in the spring following his 2011 senior season, after discovering he played much of the year with a fracture in the foot. After extensive rehabilitation, Elqutub began training for a pro career.
"We were brutally honest with Yaser about his strengths and the areas where we thought he needed to get better to play at the pro level. He worked very hard and quickly improved. We were most impressed with how he took the criticism and worked as hard as he could. All the good ones have this trait, the desire to be the best, to constantly improve, the relentless pursuit of perfection. This is the mark of a champion," said Stephen Wiggins of Student Athlete International, his agents.
