Red Sox manager Terry Francona said there's a chance that Cameron will be activated at some point during the three-game series against the Rays at Tropicana Field.
The center fielder certainly had a productive day for Double-A Portland on Sunday, belting a double in his first at-bat and finishing the day with a walkoff homer.
"He had a heck of a day," said Red Sox manager Terry Francona. "I don't think [Portland manager] Arnie [Beyeler] wants him to leave."
Cameron, who last played for the Red Sox on April 18, has been sidelined with a lower abdominal strain.
"[General manager] Theo [Epstein] is doing some scouting and travel today, but we'll kind of get together and see where we should go from here," Francona said. "Theo had a real good talk with him yesterday. We'll kind of put our heads together after the game."
Sunday marked the eighth game of Cameron's Minor League rehab assignment, which has included some interspersed breaks. He is hitting .333 in the Minors with three homers, six RBIs and a 1.187 OPS.
