As it says in the title; G Stanley Daniels was added to the practice squad, and T Dane Randolph was released. Randolph made it until the final cuts of the preseason, but was just added recently when T Jamon Meredith was signed off the practice squad by the Bills.
Not much to go on with Daniels. Some here from NFL Draft Scout, and more here from Scout.com. He sounds like a big (6'4" and 328 lbs.) and strong interior lineman. He was signed after he worked out on Monday.
Not a major move, but it does show some concern about depth on the left side of the line. Randolph had played exclusively on the right side at tackle during the preseason, while Daniels spent the preseason backing up former Pro Bowl LG Alan Faneca for the Jets. If the ankle injury to LT Chad Clifton gets worse, then they would have the option to promote Daniels to provide depth on the left side of the line.
