Former CFL running back Lawrence Phillips was convicted Tuesday on all seven counts of assault at his Los Angeles trial.
Phillips, 31, faces up to 20 years in state prison.
Sentencing is scheduled for Oct. 19.
Phillips was charged with assault with a deadly weapon for trying to run over a group of teenagers with his car at Exposition Park near Los Angeles Memorial Coliseum on Aug. 21, 2005.
According to Deputy District Attorney Todd Hicks, three of the nine teens sustained "severe bumps and bruises and cuts."
Phillips, who has remained in jail since being arrested, argued with the teenagers following a pickup football game, left the park and returned in a black Honda, which he drove onto the field and into the group of young men.
Defence attorney Leslie Ringold unsuccessfully argued that it was reckless driving, not assault.
Phillips has run afoul of the law wherever he has played football.
First, at the University of Nebraska, where he won two NCAA championships, he pleaded no contest to domestic violence charges and received probation.
Phillips was drafted sixth overall by the St. Louis Rams in 1996, butwas arrested three times in 19 months and released for insubordination.
He also spent 23 days in jail.
Phillips later joined the Miami Dolphins, but was let go after pleading no contest to striking a woman in a Florida nightclub and receiving probation.
Phillips starred briefly for the San Francisco 49ers, who released him for repeated insubordination, and in NFL Europe, where he set league records with 1,021 rushing yards and 14 touchdowns for the Barcelona Dragons.
In December 2000, he was sentenced to six months in jail after pleading no contest to felony counts of beating his girlfriend seven months earlier in Beverly Hills, Calif.
Phillips then spent two seasons in the CFL, but needed permission from the government to enter Canada because of his criminal record in the United States.
Phillips joined Montreal in 2002 and impressed with 1,022 rushing yards and 13 touchdowns on 187 carries as the Alouettes won the Grey Cup.
Next season, he briefly walked out on the Alouettes, citing a salary dispute, only to return and later be cut on May 1, 2003, for failing to meet "the minimum behavioural standards expected from the Montreal Alouettes."
It was later revealed that he was charged with sexual assault.
Phillips signed with the Calgary Stampeders on May 26, 2003, and, though he rushed for 486 yards, was released following an argument with rookie head coach Jim Barker.
