The second-year quarterback fractured the tip of the thumb on his throwing hand during the opening quarter of Saturday night's 20-15 victory over the Kansas City Chiefs. He will be sidelined at least until the opening week of the regular season.
Freeman's backups, Josh Johnson and Rudy Carpenter, each threw for a touchdown. Micheal Spurlock scored on a 53-yard reception in the second quarter, and Carpenter snapped a fourth-quarter tie with a 5-yard throw to Terrance Nunn.
The third quarterback selected in last year's draft, Freeman won three of his nine starts as a rookie.
