(CNN) -- The San Diego Chargers' Steve Foley was shot Sunday by an off-duty policeman who had followed him to his home after noticing Foley's car driving erratically, a sheriff's investigator in San Diego, California, said.
The 30-year-old, nine-year NFL veteran was shot twice; his wounds are not believed to be life-threatening, said San Diego Sheriff's Department Lt. Dennis Brugos.
The shooting came less than a week after the 6-foot, 4-inch, 265-pound linebacker was cleared on charges stemming from a scuffle with police in April.
The Coronado police officer, who was driving an unmarked car and was about 20 miles outside his jurisdiction, told investigators he started following Foley's car after he saw it about 10 miles north of San Diego on Interstate 15 northbound "weaving in lanes, traveling at speeds of between 30 and 90 mph and nearly colliding with several other vehicles on the highway."
After Foley left the expressway, the officer pulled next to the ballplayer at a red light and identified himself as a police officer, Brugos said.
When the officer ordered Foley to pull his car over, the linebacker initially drove off before stopping "after a short distance," getting out of his car and walking toward the officer, Brugos said.
At that, the police officer pulled out his handgun and verbally identified himself, warning Foley to stop walking toward him, the investigator said.
"That's a BB gun," Brugos said Foley told him.
Foley then stopped his advance, returned to his car and pulled away, driving at least two more miles before stopping on Travertine Court, the upper-class street where he lives, Brugos said.
The officer said Foley again got out of his car and walked toward him, while his passenger -- Lisa Maree Gaut -- drove alongside him in the car.
"As the suspect approached, the officer again identified himself as a police officer and that his gun was real," the police statement said.
To prove it, the officer said he fired one warning shot into bushes and two shots toward the sky.
"The male suspect reached into his pants with his right hand as he approached the officer," the police statement said. "The officer then fired at the suspect. The suspect acknowledged that he had been shot, but continued toward the officer, who then fired again at him. This time the suspect fell to the ground."
Foley was taken to Sharp Memorial Hospital, where his wounds were not considered life-threatening, Brugos said.
His companion was taken into custody for questioning, police said.
"This investigation is continuing, and it is unknown at this time what charges may be filed in this matter," said Brugos.
In April, police accused Foley of being belligerent after he complained about his illegally parked car being towed in San Diego. Charges were dropped last month.
