Though it has yet to be determined if surgery will be required, he is expected to be out for the remainder of the season. Morrison will be a free agent after the season and noted of his plight: "Yeah, it [stinks]."
Rays manager Kevin Cash told reporters that Morrison's injury will "open some at-bats" for others on the roster such as Richie Shaffer, who started at DH on Monday night against the Blue Jays.
• Matt Duffy, who had surgery on his left Achilles on Friday, was said to be doing well on Monday. The Rays' shortstop is off crutches and getting around on a scooter that allows him to put his left leg up while manuevering via the scooter. He is expected to make a return visit to North Carolina (where the surgery was performed) to be re-evaluated on Sept. 27.
Duffy is expected to be ready for Spring Training. He only played in 21 games for the Rays after coming to the team in a deal that sent Matt Moore to the Giants.
Hoping to shore up the bullpen in Cedeno's absence, left-hander Dana Eveland was selected from Triple-A Durham. To make room on the 40-man roster for Eveland, right-hander Tyler Sturdevant was designated for assignment.
