The Nets were missing three of their big men Friday in Los Angeles, and predictably got roughed up by Brook Lopez. But Quincy Acy should return Monday against the Suns, and Trevor Booker also may be back. Acy is probable after missing the last three games with a left groin strain, while Booker missed the Lakers game with a sore back. Both practiced Sunday. Jarrett Allen didn’t and is expected to be sidelined for a third consecutive game with a left foot strain. “That hurt. Any time you lose three bigs, that’s not good,” Acy said. “Anytime anybody goes down they’re missed. Everybody brings something different to the table. Coach [Kenny Atkinson] expects me to stretch the floor, so when I’m out there I guess it does open up the floor a little bit. … You always need your bigs, so we’re going to be crucial to that.” Acy, who leads the Nets in 3-point shooting (52.4 percent) and is second in 3-pointers (1.8 per game), got hurt during the loss to the Knicks at the Garden. “In the Knicks game in the third quarter I did a defensive slide and it just tightened up on me,” Acy said. “[I] got an MRI, it didn’t look too good so they kept me out.” Booker said he strained his oblique against the Nuggets, and after playing the next game against the visiting Suns had to sit out Friday. His status could be determined at Monday’s morning shoot-around.
