I googled. He left home and went off to college in 2021. From a People magazine article:
Ree Drummond just dropped son Bryce off at college to play football at University of North Texas (Go Mean Green!). The Pioneer Woman hasn’t even had time to accept that Bryce has moved away, and now she has to make plans for another one to leave the nest. That’s right, Ree and Ladd’s bonus kid Jamar is officially heading off to the University of Central Oklahoma this fall!
“Big big day!! This morning Jamar officially signed to play football at @ucobronchos starting this fall. 🙌 I’m so proud of him and so grateful for his friends, coaches, and community for supporting him in countless ways. And I’m grateful for Jamar himself—his hard work, his commitment, and his presence in our family. I love the second photo; it’s pre-pat-on-the-back from Ladd, but it sure conveys our joy. Go Jamar, and #ROLLCHOS! (Is someone choppin’ onions in here?)”
