Justin Smith has been able to return from a partially torn triceps tendon in part due to a black brace covering his left arm. 

“It’s a love-hate relationship right now,” Smith said. “It’s doing its job. It felt pretty strong. Doing anything a second time, it will be better than the first time. It should definitely be a lot better. A lot more comfortable.”

Smith has been the anchor of the 49ers' defense for several seasons.
