The Green Bay Packers have had an open spot on their roster since May 28 and finally filled it during the final week of Organized Team Activities (OTAs) on Tuesday when they announced the signing of undrafted rookie linebacker Shaun Lewis.

Lewis previously took part in the team's rookie orientation minicamp on a tryout basis back in May after a productive career at Oklahoma State.

During his four-year college stint with the Cowboys, Lewis started 45 games, making 250 tackles, 33 for a loss, four sacks, eight interceptions and seven forced fumbles. Oklahoma State went 41-11 over that span with double-digit win seasons in three of the past four years.

His senior season in Stillwater, Lewis was named first-team All-Big 12 by the league's coaches after ranking third on the team in tackles (73) and interceptions (three) in addition to making eight tackles for a loss, two forced fumbles, two fumble recoveries and eight passes broken up. He was named second-team all-conference by the Associated Press.

Lewis is 5' 11" and 226 lbs. and will wear No. 54 for the Packers. He'll have the remainder of the team's OTAs and next week's mandatory minicamp to catch up on the team's schemes before training camp starts in late July.

Now that the Packers have signed Lewis, their roster is at its full complement of 90 players. In order to potentially sign tight end Jermichael Finley or any other player, the Packers would have to clear room.

Following his senior season, Lewis was invited to the NFLPA Collegiate Bowl, where he made an interception for the winning National squad.
