Nate Robinson, Marquis Daniels out of Celtics rotation

Doc Rivers said Nate Robinson, who will return to New York tonight for the first time since being traded by the Knicks, and Marquis Daniels, are out of the playing rotation. Neither played Sunday against Cleveland.

Robinson has shot fewer than 39 percent as a Celtic and hasn’t scored in double figures since March 12. The club expected scoring punch off the bench and solid point guard play but Robinson has been tentative offensively. Rivers said he was upset that Robinson attempted a 3-point shot with 19.9 seconds left in the first quarter Friday against Houston with 19 seconds remaining on the shot clock.

Daniels has struggled since returning to the lineup in February after recovering from a torn left thumb ligament. He was signed to spell Rajon Rondo and provide solid defense, but he has gradually lost Rivers’s confidence. He averaged 9.4 points in nine games after returning from injury, but has averaged 3.7 in 18 games since.
