Memphis Grizzlies guard Derrick Rose (hamstring) remains out on Tuesday versus the Dallas Mavericks. He has missed Memphis' previous three games because of a left hamstring strain, and he'll likely miss more time moving ahead. The oft-injured 35-year-old has averaged 8.4 points and 3.4 assists in 17 games this season, so he's not rostered in many fantasy leagues. However, with Ja Morant (shoulder) done for the year, Rose could see more minutes once he's fully healthy, meaning he's worth keeping an eye on from those in deeper formats.

Sacramento Kings forward Trey Lyles (ankle) is questionable for Tuesday's game against the Detroit Pistons. The 28-year-old is battling a sprained right ankle, keeping him out of the lineup for Sunday's loss to the New Orleans Pelicans. Lyles hasn't been a consistent fantasy producer this season. However, he's a critical component of the Kings' rotation. But if Lyles misses another contest, it will at least open up more minutes for Sasha Vezenkov, who had 11 points on Sunday against the Pelicans.

Portland Trail Blazers center Deandre Ayton (knee) is doubtful for Tuesday's meeting with the New York Knicks. Ayton hasn't played since the end of December, missing time with right knee Tendinitis. There were reports he's been receiving treatment, and the doubtful tag is at least a step in the right direction. However, the 2018 No. 1 overall pick isn't expected to suit up versus the Knicks, meaning Duop Reath, amassing 15 points, 13 boards, and three blocks against the Nets on Sunday, will remain a popular fantasy option.

According to Shams Charania of The Athletic, Memphis Grizzlies guard Ja Morant (shoulder) will undergo season-ending surgery. The 24-year-old suffered a subluxation of his right shoulder on Saturday. After experiencing soreness, he underwent an MRI. Unfortunately, the results weren't good, with the MRI revealing a labral tear in Morant's shoulder. It's a tough blow for Morant, who returned to the court in December after serving a 25-game suspension. In nine appearances this season, he averaged 25.1 points, 8.1 assists, and 5.8 rebounds. The Grizzlies struggled without the 2019 No. 2 overall pick, although the team was 6-3 when he was on the floor. Nevertheless, with Morant out of the equation, Desmond Bane, Marcus Smart, and Jaren Jackson Jr. should get more scoring opportunities. Additionally, guys like Luke Kennard, Jacob Gilyard, Santi Aldama, Vince Williams Jr., and Derrick Rose (thigh) are worth monitoring in deeper fantasy leagues.

Los Angeles Lakers forward LeBron James (ankle) is currently listed as questionable for Tuesday's game against the Toronto Raptors. Fantasy managers shouldn't be worried as James seems to be a regular on the injury report. Despite that, James continues to suit up and that should continue on Tuesday. If he sits, Jarred Vanderbilt figures to move into the starting five. Fantasy managers should check back on Tuesday, but James should be fine for this game.
