It might have looked like adding injury to insult when the Cubs placed struggling, $52 million pitcher Edwin Jackson on the disabled list Thursday with a lat strain.

But Jackson remains confident he can return stronger and better from soreness that has plagued him for weeks until finally admitting the issue to the medical staff Wednesday night.

While fans on Twitter reacted with apparently bitter satisfaction over Jackson’s departure from the rotation under any circumstances, the veteran right-hander and one-time All-Star accepted responsibility for the disappointment his performance has been nearly halfway through his four-year contract.

“I’ve never been one to make excuses,” said Jackson (6-14, 6.09 ERA), who vowed to show over the rest of the deal the kind of pitcher he has been during more successful stretches of his career.
