The Week 1 NFL slate concludes tonight with Monday Night Football, which features Patrick Mahomes' return on time for the new season following his torn ACL and LCL in December. Mahomes is one of the league's most popular players, which makes any Chiefs primetime game a viable option on sports betting apps. The Chiefs host the Denver Broncos tonight for an AFC West showdown, and you can find several online sports betting options below. The Chiefs will be without defensive back Chamarri Conner (knee) and offensive tackle Josh Simmons (back) on Monday. Bet on the NFL at DraftKings Sportsbook here and get $200 in bonus bets when you bet $5+:

Chiefs (-2.5) vs. Broncos

"KC is favored in this game and it's already up to 3 in many spots, yet the masses are playing the dog," SportsLine expert Brady Kannon said. "Everything is telling me Chiefs at home, laying less than a field goal, is still nearly an auto-play. This is triple revenge for the Chiefs, who have now fallen to Denver in each of their last three meetings. Give me Kansas City to win by three or more."

Bo Nix, Broncos, anytime touchdown scorer (+600)

"The AFC West has seen a change of guard, and the biggest reason is Bo Nix's maturation as the Broncos' quarterback," SportsLine expert Micah Roberts said. "The Chiefs had won 16 straight games against the Broncos until Denver won four of the last five, including the last three. In last year's game at Kansas City, he rushed nine times for 42 yards and a TD, and I like him to score a touchdown here. He broke his ankle last season, and I don't expect him to be his normal self running the ball, but with a touchdown on the line, he'll do the unexpected for a player coming off an injury. He scored five touchdowns last year, including one at Kansas City." Bet on Broncos vs. Chiefs with the BetMGM bonus code CBSSPORTS for up to $1,500 in bonus bets:
