The Celtics signed guard John Tonje to a two-way contract as Boston continues tweaking the back-end of the roster.

TL;DR
Boston used a two-way slot on John Tonje to keep him in the system and maintain flexibility. It is a low-risk depth move that contenders make all the time.

Key Details
• Per NESN, the Celtics announced they signed 24-year-old guard John Tonje to a two-way contract.
• Per NESN, Tonje was drafted 53rd overall by Utah in 2025 and later moved to Boston in a trade.
• Per NESN, Boston previously converted Tonje to a 10-day contract before this two-way move.
• CelticsBlog included the signing in its daily roundup and roster note mix.

Breakdown
This is not a headline move, but it is a familiar contender pattern. Two-way contracts are about keeping development options close while protecting roster flexibility.

The Tonje timeline is the tell. A 10-day to a two-way is a “we want more time to evaluate you” signal without committing a full standard spot.

For Boston, these moves matter because the margins matter. If injuries hit or the schedule gets weird late, having another guard option in-house can save a week of scrambling.

What to Watch Next
• Whether Tonje gets any real minutes, or stays mostly in evaluation mode.
• If Boston makes more back-end roster tweaks as the stretch run tightens.
• How the Celtics manage two-way usage heading into the postseason.
