Toronto, ON (My Sportsbook) - Glen Grunwald was fired Thursday as general manager of the Toronto Raptors, according to various radio and print reports.

ESPN.com reported that Grunwald, who has been with the team since 1997, will be replaced by former Detroit Pistons GM Jack McCloskey.

The team has called an afternoon press conference to make what it called "a major announcement."

The struggling Raptors (30-44) have lost five straight games and 19 of their last 25 overall, including Wednesday's seven-point loss to the Golden State Warriors, who had been drubbed by the Philadelphia 76ers the night before.

With just eight games remaining in its season, Toronto is currently 1 1/2 games behind the Sixers for 10th place in the Eastern Conference and 3 1/2 games adrift of Boston for the eighth and final playoff spot.

Grunwald was hired 10 games into the 1997-98 campaign when the team was 1-9. Toronto finished 16-66 that season, but would later make the playoffs in three straight years from 2000-02.

However, an injury-plagued 2002-03 season under Lenny Wilkens led to a 24-58 record and an offseason coaching change.

In June, Grunwald hired first-time head coach Kevin O'Neill.
