Spencer (back) has been ruled out for Wednesday's game against the Nuggets.

Spencer continues to deal with lower-back soreness and will miss his third game this month. His next chance to play will come Friday in Utah. In the meantime, Lucas Williamson, Adama Bal and Rayan Rupert are candidates for increased playing time for the injury-riddled Grizzlies.

Jackson (knee) is out for Wednesday's game versus Denver.

Jackson continues to move in and out of the lineup due to nagging left knee soreness. With the forward sidelined Wednesday, fantasy managers should expect Taylor Hendricks, Toby Okani and Dariq Whitehead to each take on meaningful playing time in the frontcourt.

Gibson (foot) has been removed from the injury report ahead of Wednesday's meeting with the Nuggets.

Gibson is set to return from a one-game absence Wednesday, and he should play limited minutes off the bench. The veteran big man is averaging 3.5 points and 2.6 rebounds per game this season.

Grant (calf) is listed as out for Wednesday's game against San Antonio.

Grant will miss his fifth consecutive game Wednesday night. As a result, he will have two more chances to suit up before the start of the Play-In Tournament. With Grant out again, Scoot Henderson will presumably remain in the starting lineup.

Hendricks (thumb) isn't listed on the injury report for Wednesday's game against the Nuggets.

Hendricks sat out Monday's loss to the Cavaliers -- the second leg of a back-to-back -- due to a right thumb sprain. However, he's set to return to action Wednesday and should play a sizable role with Olivier-Maxence Prosper (ankle) doubtful and GG Jackson (knee) out.

Sharpe (calf) is doubtful for Wednesday's game versus San Antonio.

Although Sharpe still isn't expected to play Wednesday, the doubtful tag is actually an upgrade on his status that suggests he's inching closer to returning from a long layoff with a left calf strain. Scoot Henderson and Matisse Thybulle should continue to play significant minutes for Portland against the Spurs.

Castle (knee) is listed as doubtful for Wednesday's game against Portland.

Castle had a triple-double in Monday's 115-102 win over the 76ers. However, he's in danger of missing Wednesday's game against Portland due to right knee soreness. If Castle does get ruled out, Dylan Harper may find himself in the starting lineup for the first time since the 123-98 win over Memphis on March 25.

Small (thigh) has been ruled out for Wednesday's game in Denver.

This will be Small's third consecutive game on the inactive list, and it's not encouraging that he continues to get ruled out a day in advance of tipoff. For now, he should be considered highly questionable for Friday's game in Utah.

Prosper (ankle) is listed as doubtful for Wednesday's game against the Nuggets.

Prosper is expected to miss Wednesday's contest due to right ankle soreness. If the 23-year-old forward is ultimately ruled out, Taylor Hendricks, Taj Gibson and Toby Okani would be candidates to see increased playing time.

Mashack (concussion) is questionable for Wednesday's game in Denver.

Mashack has missed the past two games while in the league's concussion protocol, but this is the first time he's received the questionable tag since going down, which indicates progress. If Mashack is cleared for Wednesday's game, he could see increased playing time for the shorthanded Grizzlies.
