Team officials say Ingram had the cyst drained Thursday after it was discovered a day earlier by an MRI on his surgically repaired left knee. Ingram has been hampered by discomfort in the knee and calf during training camp.
The Eagles selected Ingram in the fifth round of the 2009 draft. He had missed his entire senior season at Florida with a torn ACL, then sat out last year when he reinjured the knee.
Ingram will not travel with the team for Friday's preseason game against the Kansas City Chiefs.
