The Detroit Pistons exercised their option to extend forward Jason Maxiell's contract through the 2008-09 season on Monday, and signed guard Gerald Fitch.

Maxiell, who was drafted with the 26th pick overall in 2005, is expected to play a key role in Detroit this season.

He played a career-high 67 games last season, averaging five points, nearly three rebounds and almost a block in just 14 minutes a game. He started eight games and took advantage of the opportunity by averaging 8.8 points, 5.6 rebounds and 2.3 blocks in 26-plus minutes a game.

"Jason is a tough, physical player on the front line who continues to grow and mature within our system," Pistons president of basketball operations Joe Dumars said in a statement. "We look forward to the contributions he will bring this season and beyond."
