Kershaw received an epidural injection for pain relief, but the club did not release an injury diagnosis or explain whether the pain was caused by a disk issue or possible herniation.
All back injuries are different, but teammate Scott Van Slyke missed nearly two months with a lower back injury and said he needed one month after receiving an epidural injection before he felt 100 percent.
Roberts was asked the chances that Kershaw, with a four-day All-Star break included, would return after 15 days. The longer he is unable to throw, the longer it will take to rebuild arm strength needed to pitch deep into games. "I can say [the chances of only 15 days are] great, but I think how his body responds to the epidural is the most telling," Roberts said before Thursday's game against the Brewers. "I don't know how it's going to be. I'm hopeful, but I can't say either way. In the coming days, we'll know how he responds to that and that will give us more direction."
