Crisp received injections Tuesday to relieve pressure in his neck, John Hickey of the Bay Area News Group reports. Crisp strained his neck after crashing into the outfield wall last Friday, the second time this season he has done so. The neck issues have been recurring for Crisp since he suffered his initial strain in May, but he's hoping the injections will allow him to return this weekend. Craig Gentry and Sam Fuld figure to share time in center in the interim.
