5:00 pm: Both players have been waived, per NBA.com’s log of official transactions.
4:25 pm: The Bucks have added center John Butler Jr. and guard Stephen Thompson Jr. to their preseason roster, according to RealGM’s transaction log. Both players signed Exhibit 10 contracts, tweets Keith Smith of Spotrac.
Butler, who will turn 23 in December, appeared in 19 NBA games for Portland in 2022/23, but has been in the G League for the past couple seasons. He finished the ’24/25 campaign with the Wisconsin Herd, averaging 7.6 points, 4.6 rebounds, 1.8 blocks, and 1.2 assists in 30.3 minutes per game across nine outings for Milwaukee’s NBAGL affiliate.
Butler was teammates during that time with Thompson, who has spent the past two seasons with the Herd. He emerged as a key contributor last season, with averages of 14.1 PPG, 4.0 RPG, 2.9 APG, and 1.0 SPG in 48 games (31.4 MPG). The former Oregon State standout was also a reliable floor-spacer for Wisconsin, knocking down 38.7% of his 6.0 three-point attempts per contest.
As is the case with most Exhibit 10 recipients at this time of year, Butler and Thompson will almost certainly be waived in the next day or two and then report back to the Herd. If they spend at least 60 days with the Bucks’ affiliate, they’ll be eligible to earn bonuses worth up to $85,300 as a result of their Exhibit 10 deals.
