Pistons guard Will Bynum has missed the team's last 15 games with a sprained left ankle.

Bynum took part in practice drills on Saturday, but he is still expected to miss Sunday's game against the Magic.

"It's frustrating in general. It's frustrating because it's my contract year. It's frustrating because we're losing. It's frustrating watching the games. It's frustrating challenging myself to stay inside of what we're doing as a team to keep myself going," Bynum said. "It's all that in one, and it's frustrating because it's new to me.

"But I'm constantly working at it and constantly trying to stay positive and just try to push through it."

He signed a two-year deal with Detroit before the 2008-09 season.

"It's tough, especially with so much negativity around as far as us losing games and negativity is the first thing that creeps up in your mind when you're down or losing something," Bynum said. "This is the time that builds character, which builds who you are, and I feel like going through these times do nothing but make you tougher."
