JACKSONVILLE, Fla. -Former Jacksonville Jaguars quarterback David Garrard will have back surgery this week, likely preventing him from signing with another team.

Garrard’s agent, Al Irby, confirmed his client’s surgery Monday.

Garrard wanted everyone to know his situation amid reports the Oakland Raiders were considering signing Garrard to replace injured starter Jason Campbell.

Garrard wrote on his Twitter page that he will have surgery to repair a herniated disc in his lower back.
