Seahawks fullback Derrick Coleman to sit out tomorrow with concussion, coach Carroll says

SEATTLE -- Seahawks fullback Derrick Coleman will sit out of Thursday's game with a concussion, coach Pete Carroll said, less than a week after he was involved in a Bellevue car crash. 

Carroll did not announce how or when the fullback got his concussion.

Coleman was arrested for investigation of vehicular assault and hit-and-run last week, but no charges have been filed. The team had suspended him until they could learn more information about the allegations. His suspension was lifted Monday.

Coleman's agents suggested the fullback may have fallen asleep on his way home from Seahawks practice, and suffered a concussion in the collision. Coleman's lawyer suggested the concussion led to his bizarre behavior following the crash.

Dan Donohoe of the King County Prosecutor’s Office said Friday the investigation into the crash will take at least a month, including the time to wait for full toxicology results.  A decision regarding charges will be made when the investigation is complete, officials said.

Bellevue police say Coleman was speeding at a high rate of speed when he hit a Honda Civic Wednesday evening.

The impact was so powerful it forced the Honda up an embankment where it flipped on to its roof. Police say a male driver of the Honda was seriously injured.

Witnesses told detectives that Coleman did not check on the injured driver but he took off instead.

A picture of the aftermath shows Derrick Coleman’s Dodge Ram on its side and a Honda rolled over along SE 36th Street.

Detectives found the Seahawks player two blocks away standing along SE 37th street, barefoot.

Police say Coleman cooperated with an officer who approached him.
