JUPITER, Fla. -- Add a couple of catchers to the Marlins' list of hobbled players.
Both starting catching candidates, Mike Rabelo and Matt Treanor, are nursing minor ailments. Rabelo was shaken up on a play at the plate on Thursday against the Nationals in Viera, Fla., when he collided with Austin Kearns.
Treanor suffered a cramp to his left calf on Wednesday.
"They're both a little banged up," manager Fredi Gonzalez said.
The hope is Rabelo, a switch-hitter, will be back in the lineup on Saturday against the Orioles in Jupiter.
The projection for Treanor is Sunday in the Marlins' final showdown with the Dodgers at Dodgertown in Vero Beach, Fla.
With Rabelo and Treanor resting, Paul Hoover is the third catcher frontrunner.
Third baseman Dallas McPherson, meanwhile, is doing limited baseball activities as he recovers from a sore groin.
McPherson said he is running fine, but he is in the process of seeing how he feels in all-out sprints.
In a camp where he has been hampered by an oblique and now a groin problem, McPherson likely will open the season at Triple-A Albuquerque.
Scott Olsen, recovering from shoulder tendinitis, and Reynel Pinto (right foot) both will pitch on Sunday in a simulated game.
