One of the nation’s top knee doctors shared a positive diagnosis with former Kentucky forward Jayden Quaintance going into the 2026 NBA Draft, revealing that his knee is not expected to be a long-term concern, KSR has learned.

That may include a second procedure to officially put the injury suffered in February 2025 behind him, however.

Dr. Riley Williams III — head team physician and orthopedic surgeon for the Brooklyn Nets and famous for performing surgery on Paul George’s gruesome open tibia-fibula fracture with USA Basketball in 2014 — gave a second opinion on Quaintance’s injured right knee that limited him to four games in Lexington and recommended a follow-up procedure that could keep him off the floor for six months. The 6-foot-11 prospect’s ACL remains fully intact and his knee can be maintained at its current state, but a clean-up is preferred for a permanent resolution.

Medical concerns led to his slide in final mock drafts — he was projected to go No. 27 overall to the Boston Celtics, according to ESPN — before ultimately landing with the San Antonio Spurs at No. 20. This procedure could lead to a delayed start to his rookie season, but the long-term reward of a healthy 15-year career in the NBA is the prize on the table. It kept teams in the lottery and late teens intrigued, despite rumors of a potential fall to the second round. Sources close to Quaintance felt San Antonio at No. 20 was a backstop for the talented forward going into draft night, an educated hunch that proved to be accurate.

Quaintance worked out for the Dallas Mavericks (No. 9, No. 30), Milwaukee Bucks (No. 10), Oklahoma City Thunder (No. 12, No. 17), Chicago Bulls (No. 15), Toronto Raptors (No. 19), San Antonio Spurs (No. 20) and Boston Celtics (No. 27) ahead of the draft, but the Thunder and Spurs were the most aggressive throughout the predraft process, sources tell KSR. Once OKC snagged Michigan’s Aday Mara at No. 12 overall, it opened the door for a move to San Antonio for the former Wildcat.

There was disappointment in Quaintance’s absence on draft night after failing to receive a green room invite, but receiving confirmation of no long-term knee concern was the biggest priority — and that came after meeting with arguably the nation’s top knee doctor before the 2026 NBA Draft began in Brooklyn on Tuesday.

Quaintance was not the top-five pick he was expected to be going into his lone season at Kentucky, but he found himself in a perfect winning situation in San Antonio next to the future face of the NBA in Victor Wembanyama, even if that includes a short-term setback.

The Kentucky Wildcats are getting ready to start a new era of their football program. In his 13 seasons as head coach, we have all become accustomed to seeing Mark Stoops teams at Kentucky play a certain way. This has been both on defense and on offense, the Wildcats have had a similar blueprint of winning games and finding success. Now, both sides of the ball will look a lot different in terms of scheme, so we will start on the defensive side and what differences you will see in 2026 under new coach Will Stein.

Old: Conservative 3-4

Mark Stoops and defensive coordinator Brad White had a lot of success in their 3-4 defense with a conservative play style, but it had plenty of weaknesses as well. With a nose tackle head up on the center and two defensive lineman playing on the inside shoulder of each offensive tackle, the defense would create pressure but couldn’t consistently finish to make them sacks. This defense required a guy like Joshua Hines-Allen to win one-on-one blocks on the edge in a dominant fashion to thrive as a defense. Since 2020, Kentucky finished top five in total sacks in the SEC just once, in 2023; every other team finished ninth or less in the conference in team sacks.

This conservative 3-4 defense allowed Kentucky to stay in similar personnel throughout the game. The conservative nature had a bend-don’t-break philosophy of keeping everything in front and making tackles. Kentucky rarely switched things up and rolled the dice with blitzes or had pre and post snap coverage rotations on the back end. It was cover 3 and cover 4 heavy, while not disguising coverages and typically sending four pass rushers at the quarterback.

New: Aggressive 4-2-5

The new scheme under defensive coordinator Jay Bateman will be the entire opposite of the old regime. This scheme will be primarily out of an even front, and we have highlighted current players on the team that will benefit from a change in technique. Mi’Quise Humphrey-Grace will switch to a traditional edge rusher lining up outside of the offensive tackle, whereas Tavion Gadson will move to a true three technique on the outside shoulder of the offensive guard and both of these players played in the same technique in the previous scheme. Both Humphrey-Grace and Gadson should have more production moving to techniques they more accurately fit.
