Clayton Kershaw threw a 40-pitch bullpen session Monday at Dodger Stadium and could face live hitters in a simulated game before the end of the week.

Kershaw, who is on the 60-day disabled list with a mild disc herniation in his lower back, said he "felt fine" sitting down between his simulated innings in the bullpen.

"That was the hard part for me before, sitting down in-between innings," he said. "Just not very comfortable to sit. Definitely a positive step there, sitting down, not even thinking about it."

Kershaw is expected to require a Minor League start or two before he is activated off the disabled list.
