PHOENIX — Barring an unforeseen obstacle, the Oakland Raiders seem certain to get approval today to relocate to Las Vegas .

Several team owners have said this 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, told The Associated Press: “Not only have no hurdles been made clear to us, but there isn’t any opposition to it.”

Added another, also speaking anonymously for the same reasons: “It’s going to happen and the sooner we do it, the better it is for the league and for the Raiders.”

Patriots owner Robert Kraft said “I hope so,” when asked if he thinks the relocation will be approved. 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. Among those:

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 his officiating staff in New York, with consultation with the ref.

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 challenges to get a third.

Entirely eliminating the three challenges per team.

Permitting a coach to challenge any officials’ decision except on scoring plays or turnovers.

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