"After sitting out the first preseason game last week, Pro Bowl safety Troy Polamalu and Pro Bowl outside linebacker James Harrison will play Thursday night against the Philadelphia Eagles at Heinz Field.

It will be Polamalu's first chance to test his rehabilitated Achilles tendon in a game, even though the 2010 NFL defensive player of the year acknowledged the real test won't come until the regular season begins Sept. 11.

"I felt fine for the little sprinting I have done in practice, but game tempo, game speed is the only real test," Polamalu said Tuesday."
