Mario Williams is back on campus.
The Buffalo Bills' star pass-rusher has returned to training camp at St. John Fisher College tonight, Bills Digest editor Mark Ludwiczak tweeted tonight.

The Bills confirmed the report to the Associated Press.
Williams has missed Buffalo's first three practices. He watched from the sideline Sunday night and was absent from the team the past two days reportedly to get a second opinion on a "sore foot."
Details about the injury have been sparse. Bills coach Doug Marrone, the only team representative who has spoken about the injury, has been unable to say which foot Williams hurt, how he hurt it or what the first diagnosis was.
