Rookie receiver Josh Morgan has been ruled out of Sunday’s game against the Rams with a groin strain.
Morgan, who has emerged as the starter at split end, sustained the injury Monday night but continued to play. He caught four passes for 54 yards, including a picturesque touchdown.
Receiver Arnaz Battle (foot) and safety Dashon Goldson (knee) have also been ruled out of action.
Running back Frank Gore (neck), tight end Delanie Walker (shoulder) and tackle Barry Sims (ankle) did not practice today, but each is expected to be available for Sunday’s game.
With Morgan and Battle out of action, first-year player Dominique Zeigler is expected to get additional playing time. In his NFL debut, Zeigler caught one pass for 22 yards. Zeigler is now the No. 2 at split end, as well as the slot. Zeigler will get on the field when the 49ers go with four wides.
