Steve Blake suffered a concussion in practice Wednesday, according to team reports. The team also listed Reggie Jackson and Aron Baynes on its injury report.
Blake, acquired in a trade this offseason to be the primary backup to Reggie Jackson to begin the year, will undergo the NBA's mandatory testing protocol and will not return until he is symptom-free. No timetable for his return has been established.
Blake was in Portland last season, playing in 81 games and averaging nearly 19 minutes per game. He averaged 4.3 points and 3.6 assists.
Point guard seems to be an early trouble spot for the Pistons. Last year's opening night starter, Brandon Jennings, is still recovering from tearing his Achilles that is expected to keep him out until sometime in December. Jackson, who signed a lucrative contract in the offseason, is also listed on the injury report with a left thigh contusion.
Baynes is listed with a sore right ankle, but it was known he would be limited with an ankle issue before training camp began.
Currently, the only healthy point guard on the Pistons' roster is Spencer Dinwiddie.
Earlier on Wednesday, Keith Langlois reported that Stan Van Gundy used rookies Stanley Johnson and Darrun Hilliard at point guard. Van Gundy said Johnson was "really good," according to Langlois.
While details are sparse, perhaps Steve Blake hurt himself while removing his tear-away khakis.
