Barring an unforeseen obstacle, the Oakland Raiders seemed certain to get approval Monday to relocate to Las Vegas.

Several team owners said last week they don’t envision a scenario where Raiders owner Mark Davis doesn’t get the required 24 votes to move the team.

Chargers owner Dean Spanos, whose team went from San Diego to Los Angeles in January, said late Sunday he “expects” the vote to go the Raiders’ way, and that he “would vote for it.”

One owner, speaking anonymously because he is not authorized to speak for the NFL, said: “Not only have no hurdles been made clear to us, but there isn’t any opposition to it.”

Yes, the NFL is about to have a third franchise move in just over a year. The Rams played last season in Los Angeles after switching from St. Louis. Earlier this year, the Chargers moved from San Diego to L.A., although they will play in a soccer stadium until the $2.6 billion facility they will share with the Rams is ready in 2019. The Rams play in the L.A. Coliseum until then.

Getting that vote on the Raiders out of the way early is a smart move because there are many other issues they will consider this week:

•?Shortening regular-season overtimes from 15 minutes to 10.

•?Allowing referees to use tablets to review plays rather than “go under the hood,” with final decisions being made by Dean Blandino and staffers in New York.

•?Prohibiting “leapers” who try to block field goals and extra points.

•?Amending the coaches’ challenge system, either by allowing a third challenge if a team is successful on one of its first two tries (now, it must be successful on both challenge) or entirely dropping the three challenges per team.

•?Letting a coach challenge any officials’ decision except on scoring plays or turnovers.

•?Adding protection for a defenseless player to a receiver running a route.

•?Eliminating the summer cutdown to 75 players, leading to just one cut day at the end of the preseason.

•?Allowing teams to opt out of using the “color rush” jerseys in Thursday night games.

•?Letting clubs negotiate with a potential hire for head coach even when his team is still playing in postseason.

•?Permitting a team to hire another team’s employee during the season if the employer consents.

Cornerbacks arrested

Chicago Bears cornerback Deiondre Hall and Green Bay Packers cornerback Makinton Dorleant were arrested outside a bar in Cedar Falls, Iowa officials say.

Hall was cited for disorderly conduct, public intoxication and interference with official acts. Dorleant was cited for interference after a report of a fight outside the bar Saturday night.

Riddick has surgery

Ameer Abdullah isn’t the only Lions running back returning from season-ending surgery.

Theo Riddick, who missed the final month of the regular season last year, had surgery on both of his wrists, which prompted his season-ending trip to injured reserve, two people familiar with the procedure told the Detroit Free Press. He’s expected to participate in team activities later this spring.

Chief medical officer

The NFL has hired Dr. Allen Sills as its chief medical officer.

Sills, 52, a neurosurgeon who has specialized in the treatment of athletes, will fill a new full-time position based in New York. He’ll work with NFL team medical staffs, the Players Association as well as experts on the league’s medical committees. He will guide the NFL’s health and research efforts and is expected to begin his new job in May.
