San Antonio Spurs point guard Tony Parker is listed day-to-day with a grade one sprained left ankle, according to head coach Greg Popovich.

Parker sustained the injury in the first half of the Spurs' 93-89 win over the Dallas Mavericks in Game 4 of their highly competitive Western Conference first-round series. Parker finished with 10 points on 5-for-14 shooting but committed four turnovers in the game.

"I guess theoretically that's a notion that you could entertain, but in the playoffs I don't think teams are ever too satisfied with wins or ever too depressed with losses," Popovich said during Tuesday's press conference.

"You just don't have time for it and it doesn't do you any good. You just move on and sometimes handling a win is tougher than handling a loss. Coming back from a loss is relatively natural. Your body reacts. But human beings have a tendency to relax when things are going well. So that's what we want to fight."

Backup point guard Patty Mills will assume a greater role for the Spurs, if the injury continues to hamper Parker on Wednesday.
