The Brooklyn Nets will have a very thin frontcourt when they take on the Denver Nuggets Tuesday night, as Rondae Hollis-Jefferson, Jarrett Allen, and Trevor Booker are all going to be sidelined due to various injuries, per Michael Gallagher of NBC Sports.

Allen hasn’t played since Oct. 29 and this will be the fourth straight contest that he’s going to miss. The former Texas Longhorn was drafted by the Nets 22nd overall in this year’s draft and has averaged 4.0 points, 2.7 rebounds, and 1.0 block in the six games he’s played so far this season. Without him, the Nets will be a little extra vulnerable in the paint against a Denver team that’s third in the NBA in points in the paint.

Booker has been out since last Friday because of back issues. He was a mild surprise last season when he put up close to a double-double average of 10.0 points and 8.0 rebounds per game. The seven-year veteran is currently playing in a contract year, which means he’s scheduled to be a free agent at the end of this season.

As for Hollis-Jefferson, the Arizona product left Monday’s game against the Phoenix Suns with a hip contusion and never returned. The severity of his injury is not yet known, but apparently, it’s something that warrants at least an absence from work. He is third on the team in scoring with 14.5 points per game.

With a banged-up frontline, Brooklyn head coach Kenny Atkinson has a small lineup to work with against Denver. Also, Quincy Acy and Tyler Zeller should both enjoy a heavy dose of minutes playing supporting roles to starter Timofey Mozgov.
