Washington Nationals slugger Michael Morse is not expected to be ready for Thursday's home opener, according to the Associated Press.
Morse, on the 15-day disabled list with a back injury, attempted to make a minor league rehab start today, but Nats manager Davey Johnson said he had to come out and undergo futher tests.
"He has no problem swinging, but unfortunately we don't have a DH," Johnson said. "I was kind of looking forward to penciling him in the lineup on Thursday."
Morse is coming off a career year -- he hit .303 for the Nats last season with 31 homers and 95 RBIs. The Nats are also concerned about closer Drew Storen, who recently had a setback in his rehab from right elbow injury and has been sent to visit Dr. James Andrews.
