This weekend, there are some underrated betting lines in both the NFL and boxing that could provide great value for bettors. In the NFL, the Houston Texans, who are currently listed as +9.5 underdogs against the Baltimore Ravens, are favored to cover the spread. Despite the Ravens' strong regular-season record, they have struggled in conference games at home and have a history of playoff struggles. The Texans have a solid defense and are expected to keep the game close, so betting on them to cover with an adjusted spread of +10.5 could be a smart move.

In boxing, Natasha Jonas is being underestimated in her fight against Mikaela Mayer. Despite being listed as an underdog, Jonas has several advantages over Mayer. Jonas has a higher knockout rate, a slight reach advantage, and more experience at the weight class they will be competing in. Additionally, Jonas is a southpaw, which Mayer has not encountered in her professional career. With the odds in her favor, betting on Jonas to win outright could be profitable.
