Tank Dell, the Houston Texans' wide receiver, is hoping to make a comeback from a knee injury he suffered a season ago that sidelined him for the entire season. The injury was caused by a touchdown catch and dislocated knee, a torn anterior cruciate ligament, medial collateral ligament and lateral collateral ligaments. Dell, who has been through two surgeries, is making steady progress in his recovery from the injury. The Texans are optimistic about Dell's medical outlook, but not rushing the process. The team expects Dell to participate in the offseason conditioning program and is looking forward to a healthy return.
