Houston Texans offensive tackle David Quessenberry has been diagnosed with lymphoma, the team announced on Tuesday.

Quessenberry had a persistent cough and experienced shortness of breath during practice last week. He had thought that he was suffering from a chest cold. Last Tuesday he was diagnosed with non-Hodgkins T Lymphoblastic Lymphoma and began treatment at MD Anderson Cancer Center in Houston later that day, according to the Houston Chronicle. He has been place on the NFL’s non-football injury list.

"Our medical community here in Houston is the best in the world," Texans general manager Rick Smith said. "We are extremely confident in the care and treatment David will receive. He is a fighter and a courageous young man, and we look forward to his full and complete recovery. We will continue to support him and his family and look forward to his return to the team."

Quessenberry told CSN Houston on Tuesday, "I'm gonna kick the crap outta this thing and come back even stronger! I will win this fight."

Quessenberry was a sixth round draft pick last year, according to ESPN. However he was on the injured reserve for his rookie season due to a broken foot. The Texans had hoped that he could provide depth to the offensive live. They have a hole to fill at left guard as rookie Xavier Su’a-Filo has missed OTA’s but is expected to be a starter.
