PITTSBURGH — Pittsburgh Steelers cornerback Ricardo Colclough said Wednesday he may have a "serious" neck injury, but he hasn't learned the results of tests that may determine how badly he is hurt.

The Steelers have said only that Colclough reported the injury after returning from their three-day break last weekend. The team hasn't played since Colclough's muffed punt inside the 10-yard line led to Cincinnati's pivotal touchdown in a 28-20 victory in Pittsburgh.

Colclough was allowed to practice Wednesday — something he wouldn't be permitted to do if the Steelers were concerned about the injury — but has been told to avoid contact for now.

"I really don't know too much about what's going on, until the test results come back and we sit down and talk about it," he said.
