FRISCO, Texas — Dallas Cowboys owner Jerry Jones said Tuesday the team is still gathering details over Ezekiel Elliott’s involvement in an altercation at a Dallas bar, the latest off-field incident for the star running back.

Elliott, who was already facing a potential suspension over the NFL’s investigation of a year-old domestic case, was involved in a dispute Sunday night that led to a man getting punched in the nose and being taken to a hospital. Dallas police said the 30-year-old man didn’t know who punched him, and the report does not mention Elliott. Dallas police also are investigating the incident.

Jones said he didn’t want to speculate about a possible suspension. An NFL spokesman said the league is looking into the latest incident “to understand the facts.” One of Elliott’s representatives didn’t return a message seeking comment.

Authorities in Columbus, Ohio, declined to prosecute the former Ohio State star over a domestic dispute with his ex-girlfriend before Elliott’s first training camp with the Cowboys last year. But the NFL’s investigation continued, and the league hasn’t cleared Elliott.

Elliott also drew unwanted attention last season when he visited a legal marijuana shop before a preseason game in Seattle. Last spring, he pulled down a woman’s shirt during a St. Patrick’s Day parade.

The 21-year-old Elliott, who led the NFL in rushing as a rookie and helped the Cowboys to the top seed in the NFC playoffs with a 13-3 record, can get suspended without any convictions, although the now-mandatory six-game ban without pay for a domestic incident is unlikely without legal involvement.

Michael Vick has some advice for Colin Kaepernick if he wants another shot in the NFL: Get a haircut.

During an appearance Monday on Fox Sports 1’s “Speak for Yourself,” Vick said the former San Francisco 49ers quarterback needs to lose his Afro or cornrows for a “clean-cut” style in order to get a job.

The former Falcons and Eagles quarterback said he was speaking from personal experience. Vick was suspended for two seasons beginning in 2007 after pleading guilty to charges in a dog fighting investigation.

Kaepernick parted ways with the 49ers in March and hasn’t been signed by another team. His decision to kneel during the national anthem last season to protest police shootings of black people became a topic of national conversation.
