Surprisingly (it was to me), the data doesn’t bear that out. Older players appear on injury reports more often (the famous “veteran maintenance days”) but do not miss a statistically-significant greater number of games per season. Of course, QB and kickers are not included in this data because they get injured far less than other positions and are the two oldest position groups, which would wildly confound the data. While I don’t have the data to back it up, I’d venture the trend
