To get their roster to 12 active players, the Spurs have signed Eric Dawson to a second 10-day contract, according to Mike Monroe of the San Antonio Express-News (via Twitter). The Spurs confirmed the move in a press release.
The Spurs initially signed Dawson to a 10-day deal in February, but didn't re-sign him when that contract expired. Monroe reported at the time that the decision was made for financial reasons. By including T.J. Ford in yesterday's Richard Jefferson/Stephen Jackson trade, the Spurs likely created the future financial flexibility to bring Dawson back.
Dawson played just two games in his first stint with the Spurs. In his NBA debut in Denver on February 21nd, he logged nearly 32 minutes, recording nine points and six rebounds.
