If he wants to continue as the New York Giants quarterback, Eli Manning is going to have to play in pain.

On Monday, Manning was diagnosed with inflamed tissue in his right foot following an MRI at the Hospital for Special Surgery in Manhattan. It’s a problem that usually develops over time and lingers.

Manning was told by team physician Russell Warren that he could play this weekend against the Oakland Raiders if he could tolerate the pain.

“It’s not as serious an injury as [the doctor] has seen before, where it’s the whole foot that’s hurting. It’s just kind of a portion of it,” Manning said.

The Giants (4-0) have listed Manning as day to day with the plantar fasciitis, which has caused soreness and swelling in the heel and arch area on the bottom of his foot.

The injury could be treated by taping the foot, stretching, cushioning the area, and using ibuprofen or any anti-inflammatory medicine, said Dr. Steven Weinfeld, chief of foot and ankle surgery of Mount Sinai’s Department of Orthopaedics in New York City. He added that cortisone injections also can help.
