Celtics head coach Ime Udoka said Richardson (COVID-19 health and safety protocols) will remain out for Monday's game against the Bucks, Brian Robb of The Springfield Republican reports.

EDGE Analysis

Richardson was placed in the NBA's health and safety protocols Friday and will now miss his third straight contest. Though Udoka didn't specify whether Richardson tested positive for the virus or was deemed a close contact of an infected person, the fact that he's now missed multiple games suggests it's the former case. The loss of Richardson should be alleviated some degree by the impending return of Jaylen Brown (hamstring), whom Udoka said would be available to play around 30 minutes Monday in his return from a five-game absence.

Richardson has entered COVID-19 protocols and is out for Friday's contest against the Suns, Shams Charania of The Athletic reports.

EDGE Analysis

Richardson will be out Friday, but the absence could extend much further, as players are often out for 10-plus days after being placed in protocols. In his absence, more minutes should be available for Romeo Langford, Grant Williams and others.

Richardson posted 11 points (4-9 FG, 1-4 3Pt, 2-4 FT) and two assists over 16 minutes in Tuesday's 117-102 road loss to the Lakers.

EDGE Analysis

After a late November illness forced Richardson to miss three games, he appeared in five straight contests. Over that span he's come off the bench and produced 10.4 points, 1.6 assists and 1.0 three-pointers over 21.8 minutes per game. Jaylen Brown's recent absence (hamstring) seems to have boosted Dennis Schroder's production more than Richardson's.

Richardson accumulated 18 points (6-11 FG, 1-4 3Pt, 5-5 FT), one rebound, two assists, one block and one steal in 27 minutes during Sunday's 109-97 victory over the Raptors.

EDGE Analysis

Richardson missed three games in a row due to illness but returned to deliver one of his finest performances of the season. He has been used off the bench this season and while that limits his upside, he can still put up decent numbers from time to time. For what is worth, he has scored in double digits in five of his last eight appearances while shooting 49.3 percent from the field in that span.

Richardson (illness) is available against the Raptors on Sunday, according to Jared Weiss of The Athletic.

EDGE Analysis

Richardson is not on the league's injury report. He will return from a three-game absence and try to improve his disappointing scoring output, which includes an average of 8.9 points across 14 games. He may see some opportunities in the coming games with the Celtics working through several injuries.

Richardson (illness) won't play Friday in San Antonio, Jay King of The Athletic reports.

EDGE Analysis

As expected, Richardson will miss his second straight game due to an illness. His next chance to return to action will be Sunday, when the Celtics travel to Toronto.

Richardson (illness) is not expected to play Friday against the Spurs.

EDGE Analysis

The same illness that kept Richardson out of Wednesday's game against Brooklyn is expected to keep him sidelined Friday. Robert Williams (illness) has already been ruled out, so Boston will likely be without two key contributors, while Jaylen Brown (conditioning) is considered questionable.

Richardson (illness) is out Wednesday against the Nets, Marc D'Amico of the Celtics' official site reports.

EDGE Analysis

An illness will keep Richardson sidelined for a second straight game, and Robert Williams (illness) has been confirmed out as well. In their absences, more minutes should funnel to Romeo Langford and Grant Williams.

Richardson (non-COVID illness) is questionable for Wednesday's contest against the Nets.

EDGE Analysis

Richardson was sidelined for Monday's win over the Rockets due to the illness, but he has a chance to return Wednesday. Jaylen Brown (injury management) is also questionable for the matchup with Brooklyn, so if both players are sidelined, then Marcus Smart, Dennis Schroder and Romeo Langford would all be candidates to see expanded roles against the Nets.

Richardson (non-COVID illness) is out for Monday's game against the Rockets, Souichi Terada of The Springfield Republican reports.

EDGE Analysis

Richardson was a late addition to the injury report, so it's not a surprise that he is unavailable. Jaylen Brown (hamstring) is returning Monday from an eight-game absence, so he will likely garner the majority of Richardson's missing minutes.
