San Antonio, TX (SportsNetwork.com) - San Antonio Spurs point guard Tony Parker is listed as day-to-day after an MRI conducted Thursday revealed a Grade 1 strain in his left hamstring.

Parker left Wednesday's series-clinching win over Portland early in the second quarter with tightness in his hamstring and did not return. He was 0-for-2 from the floor prior to exiting the eventual victory, which sent the Spurs into the Western Conference finals for the third straight year.

The six-time All-Star averaged 23 points and 6.5 assists through the first four games against the Trail Blazers.

San Antonio will start the Western Conference finals against the Oklahoma City Thunder on Monday.
