The Bears concluded their offseason program Thursday and also bolstered their roster by signing veteran tight end Tony Moeaki and defensive lineman Marquis Jackson.
Moeaki, who participated in this week's minicamp on a tryout basis, has appeared in 48 NFL games with 31 starts over five seasons with the Chiefs, Bills, Seahawks and Falcons, catching 91 passes for 1,201 yards and six touchdowns.
Moeaki's first NFL season remains his most productive. After being selected by the Chiefs in the third round of the 2010 draft out of Iowa, the 6-3, 252-pounder had 47 receptions for 556 yards and three TDs as a rookie.
