The Bengals brought in three wide receivers during the team's off day on Wednesday for a workout. According to Pro Football Talk, the three players were DeVier Posey, Colin Lockett and Donte Foster.
Lockett was a former Bengals practice squad player, signed out of San Diego State as an undrafted free agent following the 2014 draft. Lockett played in all four Bengals preseason games in 2014, generating only two receptions for 14 yards receiving, he was expected to be used on special teams for kickoff and punt returns. Lockett was released from the Bengals' practice squad in October 2014 when the team added Cobi Hamilton to the practice squad and Greg Little to the roster. He was then signed to the Washington Redskins’ practice squad in December. At San Diego State, Lockett posted 130 receptions in his collegiate career, with 1,999 yards receiving and 16 touchdown catches. He added 92 kickoff returns for 2,216 yards and three touchdowns. Lockett ran a 4.46 40-yard dash at his 2014 Pro Day, and though the Bengals are likely just doing research bringing in these players for a workout, they may be scouting Lockett for his special teams ability.
Posey is from Cincinnati and was drafted in the third round of the 2012 draft by the Texans out of Ohio State University. He appeared in 26 games with the Texans from 2012-2014 but only played in 1 game in his final season with the team. Throughout his career, Posey had 22 receptions on 40 targets netting 272 yards and 0 touchdowns. He spent training camp this year with the Jets before being released.
Foster attended Ohio University where he earned second-team All-MAC honors following his senior season and MVP honors in the Beef O'Brady's Bowl, recording 160 yards receiving. He played in 51 games at Ohio generating 2,170 yards receiving, and 21 touchdowns on 167 receptions. Foster was signed by the Minnesota Vikings as an undrafted free agent following the 2014 draft. He spent the 2014 season on the Vikings practice squad and was released during final roster cuts this September.
It's likely the Bengals were simply doing some research, potentially for their practice squad as all three players are practice squad eligible.
