ANN ARBOR, Mich. (AP) - Michigan started preseason practice without suspended players Fitz Toussaint and Frank Clark, and coach Brady Hoke gave no hint of when either will return.

"That's a decision that has to be made down the road, and I don't know when that will be," Hoke said Monday after practice. "Right now, we'll focus on the guys that are out there."

Toussaint, the starting tailback, was arrested for drunken driving. Clark, a defensive end, was charged with second-degree home invasion.

Hoke isn't concerned about Toussaint and Clark missing practice time.

"They played a lot of football for us last year," he said. "They will be fine."

Quarterback Denard Robinson said Toussaint is eager to be reinstated.

"I've been talking to Fitz, and he wants to be out on the field with us," Robinson said. "It's the first day of practice, and we've all been waiting for this. He wants to be out there just as bad as the rest of us, but right now he can't be."

Wide receiver Jerald Robinson took part in the afternoon workout after pleading guilty to a misdemeanor destruction of property charge Monday morning in Ann Arbor.

Hoke said that Robinson's punishment had concluded.

Despite his players' legal issues, Hoke was happy to be back at work. His team is the favorite in the Big Ten's Legends Division, although they will be severely tested in the opener against defending national champion Alabama on Sept. 1 in Texas.

"Today was our first day with a new football team, and that's always going to be fun," he said. "There was some excitement out there today, but there was also some chippiness, and that's what we want to see. We're going to put these players under stress, because we want Saturdays to be easy for them."

Hoke also acknowledged that, despite his team not wearing pads for the first day of practice, he was pleased to see some contact.

"These are football players, and when they've got a helmet on, they are going to run into each other a bit," he said. "We want to have a physical football team, but we also want a tough team, both mentally and physically. We need to have the confidence to play fast, and that's what we're seeing."
