The Boston Celtics continue their Western Conference road trip and head to Moda Center to take on the Portland Trail Blazers on Saturday.The Trail Blazers are coming off a disappointing 31-point blowout loss against the San Antonio Spurs. Meanwhile, the Celtics lost their last game by seven points to the Utah Jazz after a grueling battle.The Portland Trail Blazers haven't found any rhythm offensively and are, once again, abysmal on defense. They are ranked 27th in the league in defensive rating and the new head coach Chauncey Billups hasn't done anything to improve them on that side of the floor.They are 11-12 through their first 23 games and there are no signs of improvement. They recently fired GM Neil Olshey and due to the chaos in the front office and locker room, many analysts have suggested it might be time to blow up the lineup and start fresh.The Ringer@ringerDame and CJ are magic on offense but tragic on defense.

They are 8th in defensive rating, but their offense is ranked 19th in the league. They replaced coach Brad Stevens with coach Ime Udoka and the latter hasn't had the best start to his head coaching career.The Celtics are expected to be in the top five seeds of the East every season, but they are 9th right now with a 12-11 record. So far, there have been no positive signs from this team.Boston Celtics Injury ReportBoston Celtics head coach Ime UdokaThe Boston Celtics didn't play Jaylen Brown in their last game against the Jazz.

Dennis Schroder will start as the point guard and Marcus Smart will join him in the backcourt.Jayson Tatum will play the small forward role and Al Horford will be power forward as Robert Williams III takes the center position. Grant Williams and Jason Richardson will likely get the most minutes off the bench.Portland Trail BlazersThe Portland Trail Blazers have started Anfernee Simons instead of Damian Lillard at the point guard position but the former is now ruled out as well. It gives coach Chauncey Billups fewer rotation and lineup options heading into the matchup.CJ McCollum will retain his shooting guard role and Jusuf Nurkic will play his usual center position. We might see Norman Powell start as the point guard tonight with Tony Snell starting as the small forward. Robert Covington will likely play his usual power forward role.
