Sharper has some added motivation as he squares off against his brother, Texans linebacker Jamie Sharper. The brothers clashed twice while Jamie was with the Ravens, with Green Bay winning both times.
"I'm 2-0 against them right now in the times we've played each other in our careers," Darren Sharper said Thursday. "I'm looking to go 3-0 and to keep his mouth shut a little bit. But he's mouthing off. He's a little confident over there. They have a good team."
Like Sharper, Jackson is listed as probable for Sunday's game and hopes to practice Friday. Jackson is slowed by swelling in his left knee, the same knee that kept him out for more than a month after dislocating his kneecap just a few plays into the season opener at Carolina.
Breaking from routine, starting running back Ahman Green practiced Thursday. He had been resting during the Wednesday and Thursday practices because of an aggravated Achilles' tendon. Green watched Wednesday's workout, however, after getting kicked in the knee Sunday against Minnesota. He, too, is listed as probable.
As for Martin, he continues to be plagued by a left knee that's been bothering him since the preseason. He aggravated that injury against the Vikings. He's listed as questionable.
