Los Angeles Lakers guard Kobe Bryant grimaces after being injured during the second half of their NBA basketball game against the Golden State Warriors, Friday, April 12, 2013, in Los Angeles. The Lakers won 118-116.

MIAMI — Heat star LeBron James says Kobe Bryant's season-ending Achilles injury is "sad," yet also says that athletes cannot play games worried about getting hurt.

James also reiterated what he said in a tweet not long after Bryant got hurt Friday night: he has no doubt the Los Angeles Lakers star will return to the NBA.

After Miami beat Chicago on Sunday, James was asked if seeing Bryant get hurt would affect how much he decides to play in the Heat's final two regular-season games. James said if athletes play with concerns about getting hurt, "you're never going to be able to maximize your potential."

Heat coach Erik Spoelstra also weighed in on the Bryant injury, saying that seeing it made him sick to his stomach.
