Sudfeld injured his non-throwing hand Thursday night in the Eagles' preseason opening loss to the Tennessee Titans.
The injury occurred late in the first half as Sudfeld braced himself while falling to the ground as he was hit by defensive tackle Isaiah Mack and linebacker LaTroy Lewis. Mack was whistled for roughing the passer on the play.
Sudfeld is the team's No. 2 quarterback behind Carson Wentz, who has suffered season-ending injuries in back-to-back years.
Cody Kessler, who replaced Sudfeld on Thursday, and rookie Clayton Thorson are the other quarterbacks currently on the Eagles' roster.
A former sixth-round pick out of Indiana, Sudfeld connected with Marken Michel for a 75-yard touchdown prior to getting hurt and finished 10-of-18 for 177 yards.
Information from ESPN's Tim McManus was used in this report.
