HOUSTON -- In an Instagram post on Monday evening, Houston Texans offensive lineman David Quessenberry shed some more light on his plan for returning to football.

"My fight is not over," Quessenberry said. "I will not compete in the NFL until I finish my maintenance chemotherapy protocol. At which time I will strap up and take my place on the field with my teammates and coaches."

Quessenberry expressed his thoughts eloquently.

Through his fight, which began on June 6, 2014, Quessenberry has remained very optimistic. There were even times when he thought he might be able to return even while undergoing his maintenance treatments -- a much lighter program that involves chemotherapy pills. The most intense period of his cancer treatments came in the first seven months after his diagnosis.

Ultimately any decision about his return to football had to be made by Quessenberry, his doctors and the Texans' training staff.

If his treatments are finished by 2017, he'd be returning to the game after four years without playing.

"If there is anybody that can come back and play," Texans coach Bill O'Brien said, "it’s David Quessenberry."
