Thunder's Isaiah Hartenstein: Participating in practice
Hartenstein (ankle) participated in an offseason workout with the Thunder on Monday, Clemente Almanza of USA Today reports.
Hartenstein sat out FIBA qualifiers with Germany to nurse an ankle injury he sustained earlier this summer, so it's encouraging to see him back on the court ahead of training camp in the fall. The 28-year-old big man appears to be firmly on track for the start of the regular season in October, barring any setbacks along the way.

Thunder's Isaiah Hartenstein: Managing ankle injury
Hartenstein (ankle) won't play for Germany during this summer's FIBA 2027 World Cup Qualifiers, per Eurohoops.net.
The 28-year-old center is erring on the side of caution ahead of the NBA regular season, opting to sit out the international competition. It doesn't sound like there's much concern regarding his availability for the start of training camp in the fall, but fantasy managers should keep an eye on Hartenstein's status until then.

Thunder's Isaiah Hartenstein: Plans to re-sign with OKC
Hartenstein intends to sign a three-year, $75 million contract with the Thunder, Shams Charania of ESPN reports Friday.
Hartenstein will return to the Thunder after spending the last two years in Oklahoma City. The big man was a key piece in the team's championship run in 2025, and he figures to continue operating in a starting role next season. Over 47 regular-season appearances (46 starts) in 2025-26, he averaged 9.2 points, 9.4 rebounds, 3.5 assists and 1.8 combined steals-plus-blocks in 24.2 minutes per contest.

Thunder's Isaiah Hartenstein: Plays 21 minutes in Game 7 loss
Hartenstein contributed seven points (3-7 FG, 1-1 FT), five rebounds and one steal across 21 minutes during Saturday's 111-103 loss to the Spurs in Game 7 of the Western Conference Finals.
Hartenstein saw his playing time fluctuate over the course of the Western Conference Finals, and he saw less minutes in Game 7 than backup center Jaylin Williams (26). Hartenstein also finished Saturday's elimination game with a minus-14 point differential, which was worst on Oklahoma City. He has a $28.5 million team option for the 2026-27 season, and the two sides could work on an extension over the offseason. He finished the 2025-26 postseason averaging 9.1 points, 8.3 rebounds, 2.6 assists, 0.8 steals and 0.7 blocks over 23.4 minutes per contest, with three double-doubles across 15 playoff games.
