Men’s basketball Head Coach Eric Musselman said Sunday that star junior guard Rodney Rice may miss the rest of the season with a shoulder injury he sustained in late November.

“No update,” Musselman said in a news conference after Sunday’s 68-61 win over Washington State. “I would say there’s a possibility [Rice will be out for the season], but there’s no finality on what happens.”

Rice shined as USC’s starting point guard over its first six games, averaging a team-second-best 20.3 points and a team-high six assists per game. He notably scored the second triple-double in USC history Nov. 14 to cement himself as the Trojans’ breakout star before suffering the injury Nov. 25 during the Southwest Maui Invitational.

While Rice’s injury is top of mind, the Trojans (10-1, 1-1 Big Ten) are already battered just 11 games into the season, with two starters and the team’s sixth man sidelined and another starter plagued by a nagging injury. However, Musselman and company have still fought hard, climbing into the Associated Press’ Top 25 before an 84-76 loss to Washington (7-3, 1-1) on Dec. 6, though the team will likely need to get healthier if it hopes to compete come Big Ten play.

“I’m amazed that we’re 10-1, to be honest,” Musselman said, specifying that his surprise stems solely from the team’s injury situation. “I also know that we have to get a lot better.”

Though Rice performed well in the role, he wasn’t even USC’s projected starting point guard: Five-star freshman Alijah Arenas, the third-highest-ranking recruit in USC history, was expected to lead the team before he suffered a knee injury in July that was expected to sideline him for most of the season.

However, Musselman said Arenas will likely be cleared to practice sometime this week and is likely to participate in a full practice after USC’s game against the University of Texas at San Antonio (4-6) on Wednesday. Earlier this month, Musselman said that Arenas is projecting to play in a game by mid-January, aligning with the early end of his original six-to-eight month recovery timeline.

With both of USC’s top point guard options out, graduate guard Chad Baker-Mazara has stepped up for the Trojans, averaging a team-high 21.6 points per game alongside 5.5 rebounds, 2.9 assists and 1.5 blocks per game. But, he, too, has been dealing with an injury of his own — a nagging hamstring injury that took him out for a few minutes of Sunday’s win.

“On one of his strides, he felt some uncomfort,” Musselman said about why Baker-Mazara sat for part of the game. “But he went up and blocked a big shot at the end that we needed.”

The Trojans are also without their definitive sixth man, senior guard Amarion Dickerson, for three or four months due to a right hip injury, Musselman announced in a news release last week. Dickerson, who was a major spark plug off the bench, averaging 4.6 points and 3.4 rebounds in about 22 minutes per game, is likely to miss all or most of the season.

Musselman on Sunday floated the idea of USC adding an additional player to its roster midseason due to the injuries, though he did not specify where the player would come from. NCAA rules prohibit midseason transfers between Division I programs, though Musselman could look for alternative pathways to try to find his reinforcement.

“To coach with those three guys out, it’s hard,” Musselman said. “If we can somehow get another player, I’d like to get that done, too, if we can make that happen.”
