Update: Here is a link to an article with pictures of Peppers' at a concert with his injured hand. Many will remember Peppers committed to TTUN with a rap song. He opened as a rapper for "Juicy J" at a concert the other night in Ann Arbor. Juicy J gave the students one last word of wisdom before departing.  "On his way out, he offered the most quintessential Juicy J wisdom imaginable: “Smoke weed. Get high. Don’t drink and drive.” And with that, the show was over."

There were rumors about Peppers punching glass and injuring his hand but they were never corroborated as far as I know. Earlier, the Michigan Daily reported that Peppers was spotted on campus with his hand in a cast.

Now according to reports he is "working through something." Harbaugh when asked if he would play in the bowl game he replied, "We'll see."

Here is an excerpt from the article, 

"ANN ARBOR -- Michigan All-Big Ten defensive back Jabrill Peppers is "working through something" at the moment, and his status for Michigan's Citrus Bowl game against Florida is uncertain. Michigan coach Jim Harbaugh confirmed the news Saturday afternoon, but opted not to get into specifics as it relates to Peppers' injury situation. 

Asked if he'll be available for the Citrus Bowl, he replied: "We'll see."

Peppers was not in attendance at Michigan's annual team banquet earlier this week, though a Michigan spokesman said his absence was due to an "academic conflict."
