Porter, shot less than two weeks ago in Denver, is listed as doubtful for Sunday's game at Kansas City. Coach Bill Cowher said he would be careful not to rush his All-Pro linebacker back into action.
"It was good to see him out here running," Cowher said. "Like I said, we'll see. He did a lot today. We'll see how he feels (Thursday) and go from there. The biggest thing is to see what
risks are involved at this point."
Porter hasn't practiced since he was the victim of a drive-by shooting Aug. 31 in Denver. A bullet grazed his buttocks and lodged in his right thigh before being removed by the Steelers' team doctor.
"The strength is an issue; pushing off (his right leg) is an issue. He really hasn't tested it from a hitting standpoint and from an endurance standpoint," Cowher said.
Doctors told Porter he is healing rapidly and there appears to be no chance of infection in his right thigh.
The Steelers estimated last week Porter would be out two to eight weeks. Porter said Sunday he expected to be out no longer than three weeks.
