Antoine Walker has spent the past few months chasing an unlikely NBA comeback, playing in the D-League for the Idaho Stampede with hopes that perhaps he could make it back to the L. Sadly, it looks as though that won’t be happening, as the former three-time All-Star announced after a game last night that he’s officially retiring from the game. Via CSNNE: “Former Boston Celtic Antoine Walker announced his retirement from basketball on Saturday night in the Idaho Stampede locker room following their win against the Bakersfield Jam, according to a team statement. The 35 year old is expected to make a formal retirement announcement in the coming days. Marc Spears from Yahoo! Sports first reported Walker’s retirement. Walker, a 12-year NBA veteran, joined the Stampede (NBA Development League) last season and played 87 games for the team. He entered Saturday’s game averaging 9.5 points, 4.9 rebounds, and 2.3 assists per game and scored six points (2-8 FG, 0-3 3PG) and four rebounds in 20 minutes in the win.”
