Murray has been a solid starter for the Spurs. Despite suffering a season-ending ACL injury last year, Murray has been phenomenal for the team this season and is currently averaging a career-best 10.0 points, 6.0 rebounds, 4.1 assists and 1.7 steals.

The 23-year-old swingman has shown tremendous defense as well, as he is now ranked third in the league in steals at his position.  His lengthy wingspan allows him to sneak in and beat his opponents to the ball. Patty Mills should be expected to see an increased roll in the backcourt if Dejounte Murray sits out on Sunday.

On the other hand, Gay's bench production will be severely needed against the Heat. He has been doing a terrific job at his role coming off the bench even though he's averaging a career-low 10.7 points.

The 16-year veteran is also averaging 5.8 boards and 1.8 dimes. He will be missing his second consecutive game if he does not play on Sunday's game. Big man Trey Lyles is expected to see an increased role in the frontcourt if Rudy Gay doesn't play.

The Spurs are currently in the ninth seed in the Western Conference with a 17-23 record. They have struggled significantly this season, though they are two games behind the Memphis Grizzlies for the eighth seed.
