Dolphins coach Tony Sparano said Lex Hilliard would be replacing Patrick Cobbs. That is probably true, but he forgot to mention the guy taking Cobbs' vacancy on the active roster.
According to The San Jose Mercury News, the Dolphins signed running back Kory Sheets off the San Francisco practice squad on Tuesday. Sheets didn't sound all the excited about leaving his peeps in San Francisco.
"I've been with these guys all training camp, and we went through the grind together," Sheets said. "I've bonded with these guys. But this is just part of the business."
Sheets played for Purdue University. He is second on the Purdue career rush list with 3,341 yards. Mike Alstott is atop that list.
Sheets -- 5-11 and 208 pounds -- was not drafted out of Purdue.
He's got a three weeks to impress the Dolphins brass.
Note to Sheets: Find a way to show up on special teams.
