PULLMAN, Wash. -

Pullman Police plan to finish their investigation this week into an assault involving WSU football player Shalom Luani.

Luani was arrested on suspicion of second degree assault last month. Police say Luani got into a fight outside a Pullman Domino's Pizza; police say he punched a man and broke his nose. He was booked into jail and released.

Pullman Police Commander Chris Tennant told kxly4 Tuesday, he expects the investigation to be sent on to the prosecutor's office this week. He expects police will recommend some level of assault charge against Luani, but it's not clear yet what charge that would be. It's up to the prosecutor to make the final charging decision.

Assault in the first, second and third degree are felonies in Washington. 4th degree assault is a gross misdemeanor.

Luani, a senior safety from American Samoa, was a star on the Cougars defense last season. He did not play in last weekend's season opener against Eastern Washington University. Coach Mike Leach said Monday Luani will play in Saturday's game at Boise State.
