Mark Dantonio doesn't comment on personnel matters, but I do.
And there are several key personnel items from around the Big Ten. Let's round 'em up in two posts.
Here's the first:
Coach Joe Paterno said it looks "very doubtful" that starting quarterback Rob Bolden will play Saturday night against Michigan. Bolden suffered an apparent head injury in the first half of last week's win at Minnesota. Paterno didn't confirm that Bolden suffered a concussion but said the freshman "still had some memory problems" when examined by team doctors Sunday.
Bolden did some light throwing at practice Monday and will undergo more tests Wednesday morning.
If Bolden isn't cleared, Paterno will open up the competition to both Matt McGloin, who relieved Bolden against Minnesota, and Kevin Newsome.
"If they take a look at him [Wednesday] morning and they say he can practice [Wednesday] afternoon, that will be one thing," Paterno said. "If they say it looks like he'll be OK Saturday but he can't do any practicing the rest of the week, it puts me in a different spot."
Starting defensive end Jack Crawford (foot) is expected to practice today, but Paterno said the junior still is having trouble running and likely will miss the Michigan game.
"I doubt Jack will be ready," Paterno said.
Coach Danny Hope is "optimistic" that starting quarterback Rob Henry can return Saturday at Illinois after suffering a laceration on his throwing hand in last week's loss to Ohio State. Henry doesn't have ligament damage, and his status will hinge on how the wound heals and whether there are any signs of infection.
If Henry can't play, Purdue likely will start true freshman Sean Robinson, who relieved Henry against Ohio State. Robinson entered the year as the Boilers' No. 4 quarterback and a likely redshirt candidate.
Purdue might go with Henry even if the redshirt freshman can't practice this week.
"I hope he can practice some," Hope said, "and my gut feeling is if he gets the go-ahead from the doctors, that he'll get some practice opportunities. Obviously, it's going to be limited. But we're in a position right now, quarterback-wise, on the depth chart, where whether he practices much or not, if he's ready, we're going to play him. We don't have a lot of players left at that position."
It doesn't sound like receiver Justin Siller, a former starting quarterback for Purdue, will be back from his foot injury this week.
As referenced above, Dantonio refused to comment on the status of suspended and jailed cornerback Chris L. Rucker, who has missed the last two games following his Oct. 11 drunken-driving arrest. Rucker isn't listed on this week's depth chart, and I wouldn't expect to see him at Iowa. Dantonio also declined to talk about his zero-tolerance policy for players involved in the residence hall incident.
Dantonio didn't rule out receiver Keshawn Martin for the Iowa game, saying Martin's apparent foot/ankle injury is not season-ending. Martin is listed as a co-starter on the depth chart.
