Updated: Aceves latest injured Yankee

After a one-hour and 14 minute rain delay, Alfredo Aceves replaced CC Sabathia on the mound. Soon after, Aceves was hurt.

After finishing off the fifth, Aceves was forced to leave the game with two on and two outs in the sixth. Aceves seemed to slip on the mound as he delivered a pitch to Jeremy Hermida.

The Yankees say he has a stiff lower back.

Joe Girardi and trainer Steve Donohue came out to check on Aceves and then they took him out, replacing him with Boone Logan.

This adds to the Yankees' injury woes. The team announced on Saturday that Nick Johnson will be out "several weeks" with his wrist injury. They already have Curtis Granderson on the DL with a groin injury.

And the Core Four is sore with Jorge Posada, Andy Pettitte and Mariano Rivera all recovering from injuries.
