Ryan Poles said Jaylon Johnson suffered a leg injury while training on his own. Here’s what else we learned on Tuesday as Bears training camp began at Halas Hall.

Last season, Johnson once again proved that he's one of the most important players on this Bears roster -- and one of the NFL's best cornerbacks. Johnson had his second consecutive Pro Bowl season, where he forced three turnovers and recorded a career-high in tackles (53) and tackles for loss (7) while teams elected to steer clear of him when they could.
