The Memphis Grizzlies have signed Christian Koloko to a 10-day contract under a hardship exception, as reported by ESPN’s Shams Charania. With Zach Edey unavailable, the team has leaned on Santi Aldama and Jock Landale at the center position. While Koloko adds depth, his impact is expected to be limited, making him a low-priority option in standard fantasy basketball leagues.
