Westlake, Ohio ? The fiancee of Cleveland Browns running back William Green was arrested Wednesday night on charges she stabbed him in the back.

Green sustained a puncture wound under his left shoulder blade during a fight at his suburban Westlake home, police said.

Asia Gray, who earlier in the day made an emergency call to police saying Green had cut himself, was arrested for felonious assault and domestic violence.

Gray, 22, who has had two children with Green, is being held in city jail pending an arraignment in Rocky River Municipal Court. No bond has been set.

Green, currently under suspension for violating the NFL’s substance-abuse program, told police earlier in the day that he was injured when he fell down stairs.

Green’s wound, below his left shoulder blade, did not require stitches.

Police responded to a 911 call from Green’s home Wednesday morning from an upset Gray, requesting an ambulance for the second-year back.

An emergency vehicle was sent, but Green was not there when it arrived. Police Capt. Guy Turner believes Gray drove Green to St. John-Westshore Hospital accompanied by the couple’s 10-week-old baby girl. Green was treated there before being transferred to MetroHealth Medical Center in Cleveland — about 10 miles away.

The player’s sports utility vehicle was impounded, and police sealed his home before acquiring warrants and searching his residence and vehicle.

Turner said Green’s home was sealed immediately after police had determined there was one else hurt.

Green told police he was hurt accidentally.

“He said it was received when he fell going up a flight of stairs, carrying some items, including a knife,” a police release said.

Green was suspended for four games last week by the NFL for violating the league’s substance-abuse policy. He was arrested Oct. 27 on charges of drunken driving and marijuana possession. The Browns suspended him for the Nov. 9 game at Kansas City for “conduct detrimental to the team,” and the league will count that game as part of its suspension.

Under terms of his league suspension, Green is not permitted to be at the team’s training facility and the Browns are not allowed to have contact with him.

Policy said the Browns are hoping the league will make an exception and permit the club to help Green deal with his problems and aid his recovery. Browns owner Randy Lerner visited Green in the hospital, but league spokesman Steve Alic said the team did not violate league rules by seeing their player.

Green pleaded innocent to the DUI and possession charges and his driving license was suspended. He has a pretrial hearing set for Dec. 3. He is eligible to play Dec. 8 against St. Louis.

Green has had a troubled life. He was 12 when his father, a former heroin addict, died of AIDS. A year later, his mother died after contracting the disease from her husband.

While he was at Boston College, Green twice was suspended for marijuana use. His off-field infractions may have resulted in him sliding to the No. 16 overall pick in the 2002 draft despite being the top-rated back in that year’s class.

Following a slow start last season, Green rushed for 887 yards and six touchdowns. He gained 726 yards in the final seven games, leading the Browns to their first playoff appearance since 1994.

Before his suspension, Green rushed for 559 yards and one touchdown this season, but he missed Cleveland’s game at New England because of a separated right shoulder.
