Colclough's fumbled punt on only his fourth career return led to
Cincinnati's pivotal score in the Steelers' last game, a 28-20 loss
to the Bengals on Sept. 24.
He did not report having any neck problems last week but, after
returning from the weekend off, he complained of having a sore
Colclough practiced during non-contact drills for two days and
initially was listed as questionable for Sunday night's game at San
Diego, but said he feared the injury was "serious." When tests
revealed a nerve problem, the Steelers placed him on the injured
reserve list Saturday and promoted rookie cornerback Anthony Madison to the 53-man roster.
"We really don't know how" he was injured, coach Bill Cowher
said. "It's something he's been feeling for a week."
