[1] With the Southwest Texas State Bobcats, Foster averaged 12.8 points and 10.2 rebounds in his junior season and was part of the All-Southland Conference Second-Team in 1998.

Foster began the 2001–02 season as the starter, and started 48 games that year before Brad Miller was acquired in a trade with the Chicago Bulls.

Miller remained the Pacers' starting center throughout the 2002–03 season, and as such Foster was relegated back to the bench, and he produced his lowest point total yet of his career (2.1 ppg) and grabbed only 3.6 rebounds per game.

Before the 2003–04 season, Brad Miller was traded to the Sacramento Kings, and newly acquired Scot Pollard began as the starting center.
