Before putting money on an NFL game, it is a must that you read the injury report. You would not want to bet on a team only to know later that a key player has been removed from the lineup. Skill positions are WR, RB and QB; however, you also need to check the injury report on other players. No expert handicapper ever misses out on injury reports and you shouldn't too. Reports are normally released Thursday prior to a match.
Sometimes, there would be minor injuries, making it difficult to determine if a player can join or not. The common terms you can chance upon reports are probable, questionable, doubtful and out. Probable means a player has a 75% he can play; a player with a questionable status has a 50% chance of playing; when a player's status is doubtful, he only has a 25% chance to play and if the status is out, it is impossible that he can play. The percentages are not accurate but are good indicators of a player's probability to be included in the match. Normally, when he is categorized under probable or questionable, you will see him on the ground. You should confirm if the injury happened at an actual or practice game within the week.
If a popular player gets injured, it is likely that TV stations will report it, including national broadsheets. Sensible bettors will still read injury reports because they know they can find more information there. Do not just check the injuries for skill positions; they are key spots but there are others that matter too. Look at all the injuries and think how this can affect the team. For example, if a team depends largely on runs, when their strongest run blocker is wounded, their chance of winning will go down. Moreover, an injured left or right tackle in a team which relies on a passing offense could mean defeat for them.
Every field player has a big effect on the outcome of the match. The injury report of the NFL must be checked in its entirety all the time if you want to bet on a certain match.
