Matt Kemp to start rehab stint

LOS ANGELES -- Los Angeles Dodgers center fielder Matt Kemp will begin what is expected to be a two-game rehabilitation stint at Triple-A Albuquerque on Sunday.

Kemp is expected to be activated from the 15-day disabled list on Tuesday night when the Dodgers face the Milwaukee Brewers.

Kemp was sidelined May 14 with a left-hamstring strain, at a point when he was hitting .359 with 12 home runs, 28 RBI and a .446 on-base percentage.

Kemp will be joined at Albuquerque by outfielder Juan Rivera (left hamstring), who isn't eligible to be activated until Thursday night against the Brewers. But with the Isotopes leaving for New Orleans after Monday's game, Rivera is expected at that point to transfer the remainder of his rehab assignment to advanced Single-A Rancho Cucamonga.

Meanwhile, second baseman Mark Ellis finally underwent an MRI to determine the extent of the damage to his left knee after leaving the hospital, where he had been treated for an infection that might have cost him his leg if he had waited much longer to receive that treatment. He was found to have a sprain of the medial collateral ligament on the inside of the knee and a bone bruise on the outside of it.

Trainer Sue Falsone said Ellis will miss at least eight weeks.
