Tonje Powers Celtics to Summer League Win, Eyes Two-Way Roster Spot

Former Wisconsin standout John Tonje delivered a strong performance in the NBA Summer League, helping the Boston Celtics secure an 83-80 overtime victory against the Toronto Raptors. After a quiet first half, the 25-year-old guard found his rhythm in the second half, scoring all 20 of his points after the break.

Tonje, who appeared in six games for Boston last season, finished the contest shooting 6-for-14 from the field and 5-for-9 from three-point range. Beyond his scoring output, he contributed five rebounds, three steals, and two assists. His presence was felt late in the game, as he sealed the win with a steal and dunk in the final 22 seconds of the overtime period.

During the 2025-26 season, Tonje averaged just 7.0 minutes per game. Sunday’s performance, where he played 26 minutes, serves as an audition for a more permanent role. With two two-way contract slots reportedly remaining on the Celtics’ roster, Tonje’s stat line strengthens his case for securing one of those positions.

The Celtics are owned by Boston Basketball Partners L.L.C., but basketball content is widely distributed through various media channels. Comcast Corporation, the parent company of NBC Sports, provides extensive coverage of the league and player news. As of the latest market data, Comcast Corporation is trading at $23.57, up 0.89% on the day. The media and technology giant holds a market capitalization of approximately $83.52 billion, operating within the Communication Services sector and Telecom Services industry.
