Decatur police said in a statement Thursday that Biddle was shot outside a residence and was treated and released from a hospital. Police said there was no evidence Biddle caused or provoked the shooting.
"He had surgery on his hand today," Biddle's friend, Bruce Jones, told The Decatur Daily Thursday. "He told me his leg is OK, and he ought to be fine."
The 25-year-old Biddle grew up in Decatur and played college football at the University of Mississippi.
Police have not made any arrests in the case.
Biddle was promoted from the Giants' practice squad after receiver Plaxico Burress was suspended for a game in September.
