Edmonton Eskimos' wide receiver Fred Stamps underwent successful emergency abdominal surgery early Saturday at a Winnipeg hospital.
Stamps was injured early in Edmonton's 28-16 loss to the Blue Bombers on Friday night but finished the game.
After the game Stamps was in pain so the team took him to the hospital for tests, that showed there was internal bleeding and surgery was required.
"The surgery was successful and Fred will remain in hospital for a few more days," Edmonton's general manager Eric Tillman said.
"Our medical staff is projecting that he'll be sidelined four to six weeks. Football is secondary at a time like this and Fred will be in our thoughts and prayers during his recovery."
Stamps leads all CFL receivers with 33 receptions for 619 yards and five touchdowns this year. Stamps had three catches for 41 yards on the night.
