Indiana Pacers forward Bruce Brown (knee) will not return on Monday, which pushes his streak to five consecutive games missed. There has been some movement in the starting five while he's been sidelined. Aaron Nesmith, Andrew Nembhard, and Jalen Smith all joined the starting five in their last contest against the New York Knicks. It seems that Nesmith is the one who took Brown's spot while he's been absent, so whenever Brown does return, it will likely be Nesmith's minutes that take a hit. For now, Nesmith and Nembhard are both quality streaming options in deeper leagues.

San Antonio Spurs head coach Gregg Popovich said on Sunday that he expects center Zach Collins (ankle) to miss 2-to-4 weeks due to a sprained right ankle. Collins sustained the injury on Friday against the Portland Trail Blazers in a game where he was holding down the frontcourt without Victor Wembanyama, causing him to miss Sunday's game. The 26-year-old playmaking big man leaves the 5-27 Spurs without one of their top contributors for multiple weeks, producing 12.9 points, 6.0 rebounds, 3.3 assists, and 1.1 triples per game. Collins is not necessarily a must-hold fantasy player, though. San Antonio's rotation can move in many different directions, since Wembanyama's one-of-a-kind frame should allow him to seamlessly shift to the five more frequently. That means more minutes should be available for some combination of Tre Jones, Malaki Branham, and Julian Champagnie.

Toronto Raptors forward RJ Barrett and guard Immanuel Quickley are both available to make their team debuts on Monday against the Cleveland Cavaliers. Barrett and Quickley were both at morning shootaround, signaling they would be ready to rock. The former New York Knicks came over in Saturday's trade, and while it remains to be seen what type of role is initially in store for them, they should settle into very significant minutes north of the border before long. Barrett should eventually assimilate into OG Anunoby's role, which was good for 33.3 minutes per night before he was moved. Fantasy managers hope Barrett's play in his hometown of Toronto sparks greater offensive efficiency and defensive intensity. Quickley will have to battle with Dennis Schroder and Gary Trent Jr. for minutes, but he has a far greater chance to carve out a featured role than he did in the Big Apple behind All-Star Jalen Brunson.

Chicago Bulls head coach Billy Donovan says guard Zach LaVine (foot) will not travel with the team on their current two-game road trip, ruling him out until at least Friday versus the Charlotte Hornets. LaVine was ramping up as of last week as he works his way back from right foot irritation that's kept him on the shelf since Nov. 30. All fantasy managers can do is remain patient with the 28-year-old All-Star, who was netting 21.0 points, 3.4 assists, and 2.4 triples per game before the Bulls had to shut him down. Chicago has prevented their season from derailing in the meantime, but it remains to be seen if LaVine will remain in the Windy City after February's trade deadline. With Nikola Vucevic (groin) also unavailable for at least the next two nights, DeMar DeRozan and Coby White will be tasked with the heavy lifting offensively. Alex Caruso and Patrick Williams will also continue taking on extended run.

Portland Trail Blazers guard Anfernee Simons (illness) won't be available for his third straight game during Monday's meeting with the Phoenix Suns due to an illness. In his first season without sharing the backcourt alongside superstar Damian Lillard, Simons has been sensational when healthy for 11 games this year. The 24-year-old sharpshooting combo guard is dispensing third-round fantasy value in nine-category leagues with averages of 27.1 points, 5.3 assists, 3.8 threes, and 92.3% free-throw shooting on 4.7 attempts. Simons hopes to overcome whatever is ailing him by Wednesday for a date with the Dallas Mavericks, when the Blazers play the second game of what figures to be a taxing seven-game road trip. Portland's offense will run through Jerami Grant, Malcolm Brogdon, and Scoot Henderson on Monday.
