The 3-star cornerback is ranked as the No. 128 overall JUCO player and the No. 14 CB, according to 247Sports Composite.
From Tracy (Calif.) Contra Costa College, he's 6'0" and weighs 185 pounds.
Harrison signed with the Ducks in December and plans to enroll for winter term. Depending on what the Ducks' current starting cornerback tandem chooses to do, Harrison could make an immediate impact in 2014.
A 4-star cornerback Springs is ranked No. 62 overall player and the No. 8 CB.
The 5'11'', 195-pound Under Armour All-American is from San Antonio (Texas) Roosevelt.
As the No. 3 cornerback and No. 21 overall prospect in the country, Springs is the Ducks' highest-rated commit, according to 247Sports.com. Florida State and Texas have continued to pursue the physical defender, but Oregon has always been his dream school, and all indications are that he'll stick with his commitment.
The 3-star safety from Junipero Serra in Gardena, Calif., is 6'0" and weighs 185 pounds. He's ranked as the No. 71 player in the state and the No. 64 safety, according to 247Sports Composite.
Ihenacho committed to the Ducks shortly after his official visit to Eugene, Ore., in November, but he is still going through the process. Ihenacho visited Colorado in December and has a visit to Miami scheduled for late January. He appears to be making sure of his decision and is expected to remain committed to the Ducks.
The 5-star safety is ranked the No. 13 overall player and the No. 2 athlete, according to 247Sports Composite.
From Long Beach (Calif.) Poly, Smith is 6'1" and 200 pounds.
Smith likes Oregon and would be a perfect fit on either side of the ball for the Ducks, but Notre Dame, UCLA and USC remain the front-runners. After visiting Oregon in late October, Smith went to Alabama on an official visit and has been on numerous unofficial visits to see the Bruins and Trojans up close. He will officially visit USC on Jan. 17, which could seal the deal for the local school.
Biggest Competition for Commitment: Notre Dame, UCLA, USC
The 3-star safety is ranked the No. 17 player in Louisiana and the No. 29 safety, according to 247Sports Composite.
From River Ridge (LA) John Curtis, he's 5'11" and 180 pounds.
The talented defender can play either corner or safety, making him a prefect fit in a versatile defense like Oregon. The Ducks have been the favorite since extending an offer and still look to be in good shape to sign the playmaking defensive back. He will visit Ohio State and Florida State in mid-January, but the biggest threat to Oregon is a trip to UCLA a week before signing day.
Biggest Competition for Commitment: Florida State, Ohio State, UCLA
The 6'0." 185 pound safety is ranked as the No. 7 player in Idaho for the class of 2014. The 3-star was committed to Boise State until Chris Peterson left the program to take over at Washington.
Since then, Oliver has opened things up and is looking to make his choice between the Broncos, the Huskies and the Ducks.
Being so close to Boise, Oliver has yet to officially visit the school he was previously committed to. Oliver told Lars Hanson of 247Sports' Washington site, Realdawg.com, that he was unsure if he will officially visit Boise State.
"Not sure yet just because we're so close and I can go down any day and speak with them," Oliver said.
After visiting Seattle this past weekend, Oliver will make the trip to Eugene on Jan. 24 to see the Oregon program up close.
Based on what Oliver told Hanson, it appears to be an even race between the trio of programs from the Northwest.
"Right now nobody is in the lead," he said. "Boise State, Oregon and Washington are all right there. I just want to evaluate all options fully."

The Ducks are in need of reinforcements in the secondary, as they will enter spring ball without at least three starters from their 2013 unit. The Ducks have some veteran backups, but only safety Erick Dargan is a proven commodity, and he will be a senior in 2014.
Springs is the type of player who can come in and start from Day 1. If Ifo Ekpre-Olomu follows Terrance Mitchell to the NFL, the Ducks might need Springs to do just that.
As is often the case with JUCO players, Harrison is the wild card. If he comes in ready to compete and uses spring ball to adjust to the BCS level, he could become a major part of the Oregon defense.
Landing a player like Smith out of a Southern California powerhouse would benefit the Ducks for many reasons. Smith hails from Long Beach Poly, the legendary program that has sent a few players to Oregon over the years. Smith is in the same mold as Lee, in that he could be a standout safety or an elite wide receiver.
Landing either of the 5-star athletes would not only give the Ducks a huge boost on the field in 2014 but also on the recruiting trail.
