"Dr. Stewart from Tulane said he's good after reading the results of an MRI," father Noel Ellis Sr. explained. "The coaching staff is just taking precautions until the regular season begins."
"Noel had two picks against Destrehan last year," dad said. "He had a pick-six and basically locked down one side of the field. Rickey is an outstanding player. I met his dad in Atlanta through a mutual friend.
"Rickey is a standout wide receiver. I haven't seen him at cornerback, but he's an exceptional player."
Karr has appeared in the last two Class 4A state title games and finished runner-up each time.
"The team is putting the pieces together on the offensive side of the ball," Ellis said. "They're looking to establish a number two or number three wide receiver behind Rasheed Davis.
"Speedy (QB/WR Devante Noil) has been playing wide receiver during scrimmages so our number two quarterback will be ready just in case something happens. Last year in the state championship game, Speedy went down with an injury and the backup hadn't had many reps."
Ellis isn't the only New Orleans area player committed to the Aggies, as Warren Easton LB Edward Williams is also an A&M pledge.
"I was roommates at Tulane with Jerry Phillips, who is the position coach for Williams at Easton," dad said. "He called and asked me to look at Edward's YouTube highlights.
"Edward is a gamer, an outright stud. He plays linebacker and will also put his hand on the ground and play d-line."
Ellis said his son has also spoken with Laquvionte Gonzalez, a four-star WR and A&M commit from Cedar Hill (Tx.).
"They talked at The Opening," dad recalled. "I don't think Noel has had much contact with the other commits. He's a pretty humble guy who doesn't like the limelight."
