Rob Bagg has decided to go under the knife again.
The Saskatchewan Roughriders receiver will undergo season-ending surgery to repair a torn anterior cruciate ligament in his left knee.
"A lot of things went into the decision," said Bagg. "The fact if you play on a knee that doesn't have an ACL, you can cause further damage.
"While I'm not the youngest (player), I still feel that I'm fairly young and that I have some football ahead of me."
The 27-year-old native of Kingston, Ont., missed all of last season after undergoing two operations for a torn ACL in his right knee. Bagg injured his left knee in the first quarter of Saskatchewan's 17-1 home win over the Edmonton Eskimos on July 8.
Originally, Bagg believed he had suffered a hamstring injury until further examination revealed the true extent of the ailment. Bagg had six catches for 69 yards in his three appearances this season, his fifth with the Riders.
