Richards won't return to Wednesday's game against the 76ers due to a right elbow issue, K.C. Johnson of Chicago Sports Network reports.

The severity of Richards' elbow injury isn't yet known, but with Friday's game in Oklahoma City being the first of a back-to-back set, it could be tough for Richards to return for that one. Patrick Williams started at center for the second half of Wednesday's game, so he could be in line for major minutes if Richards and Jalen Smith (calf) need to skip some games.

Williams (knee) will play Wednesday against the Bucks, Danny Marang of 1080 The Fan Portland reports.

Williams is back after a one-game absence, which could result in Yang Hansen getting bumped from the rotation. Williams is averaging 6.8 points, 7.0 rebounds and 1.5 blocks per game this season.

Richards will start Wednesday versus the 76ers.

Josh Giddey, Tre Jones, Matas Buzelis and Jalen Smith will join Richards in the first unit for a second straight game. Through five starts this season, Richards has recorded averages of 9.0 points, 7.2 rebounds and 1.2 swats per contest on 47/43/55 shooting splits.

Hayes is in the starting lineup for Wednesday's matchup with the Pacers, Dave McMenamin of ESPN.com reports.

Hayes will get a spot-start with Deandre Ayton (back) unavailable, and it'll be Luka Doncic, Austin Reaves, LeBron James and Jake LaRavia joining Hayes in the first unit for Wednesday's game. Through eight starts this season, Hayes has posted averages of 11.4 points, 4.5 rebounds, 2.0 assists and 1.0 steals per game.

Embiid (oblique) will play in Wednesday's game against the Bulls, Adam Aaronson of PhillyVoice.com reports.

Embiid will return from a 13-game absence due to a strained right oblique. His return will mean fewer opportunities for Adem Bona and Andre Drummond. However, per Aaronson, Nick Nurse said Wednesday that the 76ers likely won't "go overboard" with Embiid's minutes.

The Celtics recalled Williams from the G League's Maine Celtics on Wednesday.

Williams has rejoined Boston ahead of Wednesday's game against the Thunder, but he's unlikely to be featured in the rotation. The rookie second-round pick saw extended run Tuesday in Maine's 130-105 win over the Cleveland Charge, finishing with 13 points (5-9 FG, 1-1 3Pt, 1-4 FT), nine rebounds, four blocks and one assist in 27 minutes.

Duren (knee) is available for Wednesday's game against the Hawks.

Despite being a late addition to the injury report, Duren is playing through knee soreness Wednesday. The All-Star big man has recorded six double-doubles in the past seven games, during which Duren has averaged 23.9 points, 10.4 rebounds and 1.1 assists in 27.1 minutes per contest while shooting a potent 70.9 percent from the floor.

Ayton (back) has been downgraded to out for Wednesday's game against the Pacers, Ryan Ward of SI.com reports.

Ayton was a late addition to the Lakers' injury report Wednesday morning due to back soreness. The issue will prevent the veteran big man from suiting up, which will likely allow Jaxson Hayes and Jarred Vanderbilt to step into larger roles. Ayton's next chance to play will come Friday against Brooklyn.

The Knicks recalled Hukporti from the G League's Westchester Knicks on Thursday.

As expected, Hukporti will rejoin the Knicks ahead of their next game Thursday in Charlotte after a brief stint in the G League. The second-year big man suited up for Westchester in Tuesday's 114-104 win over the Long Island Nets, finishing with 32 points (13-23 FG, 1-5 3Pt, 3-5 FT), 10 rebounds, five assists, four blocks and one steal in 37 minutes.

Turner is questionable for Wednesday's game against Portland with right calf soreness.

Turner is a late addition to the injury report, and he's been nursing calf issues for the past week or so. With Bobby Portis' (wrist) status also up in the air Wednesday, the Bucks may need to turn to Jericho Sims and Pete Nance to both take on a featured role in the frontcourt.
