The 23-year-old said he was diagnosed with the disease of the lymph nodes on Dec. 1.
"Through God's grace, I'm blessed to say that I'm currently in remission! I am grateful for the love from my family and friends, and support from the Texans organization and my doctors," he said in a statement. "My next objective is to complete my treatments, then get back to playing the game that I love. Thank you for your prayers and support as I continue this journey."
Horton was a fourth-round pick in last year's draft after playing collegiately at both New Mexico and TCU.
