As the NBA playoffs progress,John Caldwell it's becoming even more of a challenge for teams to avoid the injury bug. This season, that also includes the head coaches.

Just two days after Minnesota Timberwolves coach Chris Finch suffered a ruptured patellar tendon in a collision with one of his own players, Nick Nurse of the Philadelphia 76ers apparently injured his hand when he slammed it in frustration over a referee's call during Tuesday's game against the New York Knicks.

According to a report from SNY, Nurse injured his finger to the point where he "couldn't draw plays up in the second half because he couldn't grip a marker."

According to the report, it's unclear if Nurse broke his finger or merely sprained it.

The Sixers rallied behind their injured coach to force Game 6 in the series with a thrilling 112-106 overtime win over the Knicks on Tuesday.
