The NBA has told teams it’s going ahead with replacement referees, days after the league thought a deal had been reached with locked-out officials.

The league sent a memo yesterday informing teams it had “no expectation of concluding a timely labor contract.” The memo, obtained by the AP, follows the latest failure in negotiations.

According to the memo, the sides had agreed in principle on a new two-year deal Friday. But the National Basketball Referees Association rejected the NBA’s proposal Sunday.

The memo alludes to the reversal, saying, “this is not the first time that commitments made by the NBRA’s negotiators were not met.”
