Ferguson (elbow) was placed on the 10-day injured list Wednesday, Eric Stephen of SBNation.com reports.
The results of Ferguson's MRI have yet to be released, but the Dodgers evidently don't believe he'll be ready to pitch at any point in the next 10 days. He's likely thrown his last pitch of the regular season, though he could appear in one of the final two games of the campaign if he returns after the minimum 10 days. Josh Sborz was recalled to take his place in the pen.
