New York Giants tight end Daniel Fells is at risk of having his foot amputated, as he is battling a persistent Methicillin-resistant Staphylococcus aureus (MRSA) infection, according to NFL reporter Ian Rapoport.

Fells was placed in an intensive care unit on Friday, and reportedly has had five surgeries. More are likely to come, according to Rapoport. Saturday night doctors were fighting to save Fells' foot, and stop the infection from spreading.

The Giants organization has taken all possible precautions after learning about Fells' staph infection, as the East Rutherford practice facility underwent a serious cleaning this week, according to Ralph Vacchiano and Bernie Augustine of the New York Daily News.

Fells' infection reportedly stemmed from a cortisone shot he was given to treat an ankle and toe injury, per Rapoport.

Fells is in his eighth season in the NFL, and he has been with the Giants since 2014. The tight end from Anaheim, California played college football at UC Davis.

Fells was placed on injured reserve this past Monday, but the concern is more about his health than his return to football. Fells and the doctors are likely trying to stop the infection and save his foot, rather than worrying about his football career.
