PITTSBURGH (AP) Heath Miller knows his football career isn't over, just paused. When the injured Pittsburgh Steelers Pro Bowl tight end will be able to hit the "play" button again is anybody's guess.

Miller included.

While allowing there's "a chance" his surgically repaired right knee could be ready before the season opener against Tennessee on Sept. 8, Miller thinks it's too early to project just when he'll slip on his No. 83 jersey and return to his job as quarterback Ben Roethlisberger's favorite target.
