Steelers running backs coach Kirby Wilson sustained moderate to severe burns after a fire broke out at his north suburban Pittsburgh home around 3 a.m. ET Friday.

He will not travel with the team to Denver, and is currently hospitalized in Pittsburgh.

Wilson has been with the team for the last five seasons, and is well respected among the team. His work with Rashard Mendenhall and Willie Parker produced outstanding results.

In almost an "adding injury to insult and injury" situation, Mendenhall tore his ACL in Pittsburgh's Week 17 win over Cleveland, and Wilson spent the time this week preparing former undrafted free agent Isaac Redman to make his first career playoff start.

The Steelers will be without FS Ryan Clark for a medical reason as well. Injuries continue to pile up for the defending AFC Champions, as they head into a Wild Card round playoff game with the AFC West champion Broncos.

From the Steelers web site:

We know that he has the best medical care in the country treating him. The entire organization is praying for Kirby to have a full recovery and we will be by his side through this difficult time.
