Doc Rivers said his Philadelphia 76ers "ran out of gas" in their loss on Monday to the New York Knicks. As they have for the last week or so, the Sixers ran an eight-man rotation against the Knicks.

That's not unusual for parts of the NBA season. However, it's out of necessity for Philadelphia right now. Rivers knows he's going to have to trust some rookies and expand his rotation some.

Philadelphia is currently without Joel Embiid, Tobias Harris, Isaiah Joe, and Matisse Thybulle due to the NBA's Health and Safety Protocols. In addition, Two-Way player Grant Riller is out with a knee injury. Ben Simmons also hasn't returned to this point.

Rivers said he'll expand his rotation to 10 players to help ease the burden on his tired roster. "I don't know who that 10 is, but we have to, " said Rivers.
