7:40 p.m.: That’s it for the day. Thanks for reading, and be sure to read all of our postgame coverage on reviewjournal.com.

7:36 p.m.: Mahomes won the MVP with what wasn’t a vintage performance until the fourth quarter. He was the +125 favorite to win.

7:13 p.m.: Oh, man. Those deep kneeldowns from Mahomes pushed his rushing yards down to 28, meaning the under 31½ cashed after he had 38 yards at one point. As bad a beat on a prop as can be.

6:34 p.m.: It’s not over yet. Mahomes hits Kelce for a 1-yard TD pass. 49ers lead 20-17 with 6:13 to go. 49ers now -230 on the live line (Chiefs +185). Kelce will score a TD cashes at -110.

4:13 p.m.: At least Circa doesn’t have to sweat a long snapper scoring first anymore.

4:10 p.m.: It was almost Damien Williams, then it was almost Darwin Thompson, then it is Patrick Mahomes scoring the first TD of the Super Bowl on a 1-yard run. Chiefs 7, 49ers 3 with 31 seconds left in the first quarter. Mahomes was 14-1 to score first at the Westgate, 22-1 at Circa.

4:09 p.m.: A lot of first TD drama happening.

4:05 p.m.: Mahomes’ first rush will be over 4½ yards cashes at -120, but we’ll have to check the spot after the fumble to see if it’s a first down.

4:01 p.m.: Travis Kelce’s first reception goes under 10½ yards.

3:58 p.m.: Tyreek Hill’s first reception went under 12½ yards.

3:56 p.m.: Will Gould kick a field goal in the first quarter cashed at +190.

3:53 p.m.: Robbie Gould makes a 38-yard field goal, and the 49ers take a 3-0 lead with 7:57 left in the first quarter.

3:47 p.m.: 49ers ripping off some nice gains. George Kittle goes over 10½ yards on his first catch. Deebo Samuel runs for 32 yards to smash his 12½-yard total for the game.

3:45 p.m.: 49ers get the ball, and Tevin Coleman loses a yard on first down. First carry under 3½ yards (-120). Interesting that he’s out there instead of Raheem Mostert.

3:44 p.m.: Patrick Mahomes’ first pass will be incomplete cashes at +170.

3:42 p.m.: First play is a 7-yard run by Damien Williams for the Chiefs. First rush over 3½ yards (+110 odds).

3:38 p.m.: FYI, I will be using the lines from the Westgate as of about an hour ago to grade the props. If you got a better line or price, that’s the name of the game.

3:37 p.m.: The first thing will be checking the flurry of firsts to start the game, as basically every offensive player has a line on the distance of his first rush/reception.

3:35 p.m.: The first winner of the day is … tails on the coin flip, anywhere from -105 to -102 around town depending on the kindness of the sportsbook.

3:27 p.m.: Despite a lot of media discussion, you cannot bet on the length of the national anthem in Las Vegas. Todd Dewey wrote about that this week here. (That was definitely under two minutes, though.)

3:23 p.m.: We’re closing in on kickoff. One last look around the market: Still mostly Chiefs -1½, total 53. Westgate at Chiefs -2, William Hill and CG at 1. Golden Nugget at 54 on the total; Station, Wynn and Boyd at 53½; Circa down to 52½.

Chiefs as high as -130 on the money line, low as -114 at South Point. 49ers as high as +110, as low as even-money.

2:34 p.m.: In case anyone has props involving him, 49ers running back Tevin Coleman is active, as expected, though Jeff Wilson is suiting up as the fourth running back just in case.

2:17 p.m.: Won’t do too much with the cross-sport props, but the Golden Knights’ 3-0 victory over the Nashville Predators on Saturday might have set up a few bettors well for today.

One Westgate prop had Knights shots on goals -3½ vs. Chiefs points. With 39 shots from the Knights, KC will have to get to 36 for its bettors to cash. Another prop had Marc-Andre Fleury saves -3½ vs. 49ers points. Fleury only had to make 19 saves in a dominant defensive night for Vegas, meaning 49ers backers need only 16 points to cash in.

1:30 p.m.: The Westgate has gone to Chiefs -2, but the consensus line remains Chiefs -1½, total 53½. South Point and William Hill are at Chiefs -1. CG Technology and the Golden Nugget have the total at 54, and Circa Sports and Treasure Island are at 53.

As for the money line, the Chiefs are as high as -135 at CG and the Westgate and as low as -116 at South Point. The 49ers are as high as +115 at CG and the Westgate and as low as even-money at several books around town.
