Markieff Morris had missed only one regular-season game over the last three seasons entering the 2015-16 campaign.
In the past two months, the Phoenix Suns power forward has watched his teammates from the sidelines a total of 11 times.
If the Kansas product wishes to rejoin the Suns, he must apologize to his coaches and teammates, a league source told Yahoo Sports' Marc J. Spears. Morris will also reportedly be asked by GM Ryan McDonough to make a renewed commitment to the team as well as attend all Suns and NBA community events.
Morris tweeted an apology to head coach Jeff Hornacek and his teammates on Dec. 24 and sent a remorseful text message to Hornacek, leaving those within Morris' camp confused as to why another apology is necessary, Spears reports. However, Morris is expected to do all that's asked of him during Tuesday's meeting, the league source told Spears.
Earlier in December, amid his prolonged bout of bench-riding, Morris brushed off his reduced role.
"I've been through way worse than this," he said. "Way tougher stuff than this. On a scale of one to 10, this is like a two to me. This doesn't hurt me."
The 12-21 Suns could certainly use the old version of Morris back - the player who averaged 15.3 points and 6.2 rebounds, justifying his four-year, $32-million contract - but the disgruntled twin apparently won't be able to sniff a minute of playing time until he delivers one last mea culpa.
