Andre Roberson returned to Oklahoma City Thunder practice for the first time in almost a year, participating in contact and 5-on-5 drills.
Roberson ruptured his patellar tendon in January 2018, and has experienced several setbacks in his rehab.
"He looked really, really good in terms of the way he was moving ... we'll see how he can continue to build up and develop here over the next week, but he was out there today and he participated in everything," said Donovan.
It is unclear how Roberson will fit into the Thunder team this season.
The 28-year-old Roberson will be an unrestricted free agent after this year.
