Dallas Mavericks guard/forward Caleb Martin (hip) has been upgraded to available on the injury report, meaning he is set to make his debut for the team in Friday's matchup against the Memphis Grizzlies. Martin arrived in Dallas with a hip injury on Feb. 4 but is finally ready to make his first appearance with the Mavericks. He is expected to play around 15 minutes. Fantasy managers may not get much value from Martin on Friday, but he could turn into a significant asset once he has found his rhythm, especially since the Mavericks are short on healthy players.

Boston Celtics forward Jaylen Brown (knee) is off the injury report heading into Saturday's showdown with the Lakers. He wasn't available for Thursday's win over the Philadelphia 76ers. Jayson Tatum, who had 35 points, moved over to the three, with Neemias Queta and Luke Kornet entering the starting lineup. But with Brown back in the equation and Al Horford also off the injury report, Queta and Kornet will head back to the bench, virtually eliminating both of their fantasy potential.

Boston Celtics center Kristaps Porzingis (illness) is questionable for Saturday's game against the visiting Lakers. He's missed the last four contests because of an illness. But it appears the 29-year-old has a better chance of returning to the lineup. Al Horford, who didn't play on Thursday versus Philadelphia, is off the injury report, meaning he should slide into the starting lineup if Porzingis doesn't play. Luke Kornet, coming off a nine-point, seven-rebound, four-block showing, will likely head back to the bench.

Milwaukee Bucks forward Giannis Antetokounmpo (calf) is listed as probable ahead of Saturday's game against the Orlando Magic. The superstar forward remains a regular on the injury report, but has played in eight straight games. It doesn't seem that the calf issue is impacting him on the court considering Antetokounmpo has five double doubles in his last six games. Fantasy managers should expect Antetokounmpo to be out there, barring any pre-game setbacks.

Memphis Grizzlies guard/forward John Konchar (knee) will be active on Friday against the Dallas Mavericks. He didn't play on Wednesday against the Oklahoma City Thunder due to knee soreness, but Memphis has upgraded his status from questionable to available for Friday's game. Konchar currently serves as a depth player for the Grizzlies and is not expected to have a significant role on Friday. So far this season, he has averaged 2.5 points and 3.4 rebounds in 12.8 minutes per game.
