Part of their young core comprises of Johnathan Isaac and Markelle Fultz, both of whom are long-term absentees.Rookie Cole Anthony has also been absent since the end of February. He has a rib injury and is still some way away from making a return. Meanwhile, Terrence Ross, James Ennis III and Michael Carter-Williams were all unavailable in the win over the Brooklyn Nets and remain questionable for Sunday's fixture.Boston CelticsTristan Thompson, along with Romeo Longford, is still yet to return after being sidelined because of the league's COVID-19 protocols. Thompson has been a regular starter for the Boston Celtics as their rim protector, but he is not likely to feature till early next week. Meanwhile, second-year wing Langford was prepared to feature for the first time this season. But he got sidelined because of the league's health and safety protocols and is likely to be available next week.Orlando Magic vs Boston Celtics Predicted LineupsOrlando MagicThe win over the Brooklyn Nets came as a surprise for the Orlando Magic. That's because the Magic have struggled on offense this season, which is evident in them having the fourth-worst efficiency. Aaron Gordon and Evan Fournier's 30+ point nights made up for the Magic's lack of bench depth, as they missed Terrence Ross, who erupted for 31 points against the Heat last weekend.Aaron Gordon heats up for a season high in the @OrlandoMagic win over BK!@Double0AG: 38 PTS, 7-8 3PM pic.twitter.com/PTBIJR7qtC— NBA (@NBA) March 20, 2021The Orlando Magic are likely to start with the same five they had in their last two games.Boston CelticsBoston Celtics star Jaylen BrownAlthough there could be changes to the Boston Celtics lineup in the coming days prior to the trade deadline, Brad Stevens will likely stick with the same players who started against the Sacramento Kings.Stevens has been rotating his side significantly in recent games, trialling Semi Ojeleye as a starter and Marcus Smart from the bench. With Tristan Thompson sidelined, Daniel Theis has seen minutes at center rather than as a forward. The German, however, is yet to prove his consistency, an area which the Boston Celtics front office will likely seek some improvement.Jaylen Brown and Jayson Tatum have been doing their best to carry the Boston Celtics, with both averaging over 24 points on the season. However, with Kemba Walker proving to be a hit and miss, the C's may wish they had Gordon Hayward in green and white as their third scorer.Orlando Magic vs Boston Celtics Predicted Starting 5sOrlando MagicG Evan Fournier, G Chasson Randle, F Aaron Gordon, F Al-Farouq Aminu, C Nikola Vucevic.Boston CelticsG Kemba Walker, G Marcus Smart, F Jaylen Brown, F Jayson Tatum, C Daniel Theis.
