Cruz (hand) will remain on his rehab assignment with Double-A Altoona at least through the weekend, Colin Beazley of the Pittsburgh Post-Gazette reports.
The Pirates hadn't previously ruled out a return from the 60-day injured list for Cruz this weekend against the Red Sox, but they've opted to give him more time. Cruz has gone 2-for-13 with a 3:6 BB:K through his first four rehab games between Altoona and Triple-A Indianapolis. He has not yet started back-to-back games in center field, and the Pirates likely want him to check that box before being reinstated. Cruz has been shelved since mid-June with a fractured hand.
