The Buffalo Bills have signed defensive lineman Jarron Gilbert to their active roster, according to a tweet from Jenny Vrentas of the Newark Star-Ledger. Gilbert was on the New York Jets practice squad, and will be guaranteed a spot on the Bills' 53-man through the rest of the 2011 season.

Like tight end Fendi Onobun, whom the Bills signed a week ago, Gilbert is an athletic prospect who hasn't yet found solid footing in the NFL. He was drafted by the Chicago Bears in the third round of the 2009 NFL Draft after a successful career as a defensive end at San Jose State. He made waves by jumping out of a pool prior to the draft.

The Bears waived Gilbert in September of 2010, and the Jets signed him to their practice squad. He spent less than a month on their active roster in 2010 before being released and re-signed to the practice squad. After spending camp with the Jets, he was among the final cuts and placed back on the practice squad. He was released and subsequently re-signed to the Jets practice squad in November.

To make room for Gilbert, the Bills released LB Antonio Coleman. It's unlikely Gilbert will be active this weekend when the Bills take on the Miami Dolphins.
