Coach Chuck Pagano said that Bradshaw met with medical specialists Thursday, and the player and doctors will decide what's best.
Bradshaw hasn't practiced for two weeks after he took a hit in the opening series against the San Francisco 49ers two weeks ago. He finished the game with 19 carries for 95 yards and a touchdown, but hasn't practiced or played since. Bradshaw has 41 carries for 186 yards and seven catches for 42 yards this season.
He could have neck surgery or he let the injury heal on its own, a person with knowledge of the medical options told The Associated Press late Thursday. The person spoke on condition of anonymity because the team has not provided specific details about the injury.
Losing Bradshaw would be another blow for Indy (3-1), which shares the AFC South lead with Tennessee despite losing three offensive starters with season-ending injuries - tight end Dwayne Allen (hip), running back Vick Ballard (knee) and left guard Donald Thomas (quad).
The Giants released Bradshaw as part of last winter's roster purge. He ran for 1,015 yards on 221 carries (4.6 yards per carry) and scored six touchdowns in 2012, missing four games with injuries. In six seasons with New York, Bradshaw rushed for 4,232 yards and 32 touchdowns and won two Super Bowl rings.
