Boston Red Sox reliever Joely Rodriguez's season could be over following another setback in the left-hander's injury-riddled campaign, manager Alex Cora said Sunday.

On the 15-day injured list since July 31 with right hip inflammation, the 31-year-old Rodriguez felt something in the upper hip when he was throwing a bullpen session a few days ago.

"It's tough because he was throwing the ball well," Cora said. "The upper hip, the other side of it."
