CLEVELAND (AP) — Cavaliers star point guard Kyrie Irving will miss at least one month with a broken finger.

The NBA’s reigning rookie of the year fractured his left index finger on Saturday against Dallas. The team initially said the finger was only bruised and he played against Philadelphia on Sunday, scoring a season-low 9 points as Cleveland dropped its sixth straight game.

The Cavs said tests on Irving’s finger revealed a non-displaced fracture. He will be out a month and re-evaluated in two weeks.

It’s the latest injury for Irving, who broke his right hand during a summer practice when he slammed it on a padded wall. The 20-year-old played in just 11 games at Duke because of a foot injury.

Also, the Cavs said forward Tristan Thompson sustained a nasal fracture against the Sixers. He will be fitted with a protective mask.
