HOUSTON - KPRC is reporting a Houston firefighter was injured when a SUV registered to former Denver Broncos linebacker Brian Iwuh slammed into the back of a parked fire truck just after 2 a.m. Monday.

The firefighter was helping a disabled motorist when the SUV struck the fire truck. The firefighter was taken to the hospital with minor injuries but is expected to be okay.

Crash investigators told KPRC, an NBC affiliate in Houston, the fire truck was parked on Highway 288 near the Highway 59 interchange with its lights and sirens on when it was hit.

The man driving the black Range Rover was trapped and had to be cut out of the vehicle.

The identity of the driver of the Range Rover has not been released but KPRC says the vehicle is registered to Iwuh.

Iwuh played college football for the University of Colorado before being drafted by the NFL in 2006. He played four seasons with the Jacksonville Jaguars and two seasons with the Chicago Bears before he joined the Denver Broncos for the 2011-2012 playoffs.

Iwuh retired from the NFL in April 2012.

Investigators are working to determine the cause of the accident.
