4:44pm: The Bears announced that running back Senorise Perry is headed to the IR, as Jahns tweets.
The Bears also claimed tight end Gannon Sinclair off waivers from the Cardinals and released guard Lucas Nix, per Jahns (link).
With that, the Bears are at the 75-man limit.
3:47pm: The Bears have claimed Zac Dysert, who was waived Monday by the Broncos, team sources tell Adam Jahns of the Chicago Tribune. Dysert is expected to play Thursday night in the Bears’ final preseason game against the Browns.
Dysert was a seventh-round pick out of Miami of Ohio in 2013 and Jahns hears that Bears offensive coordinator Adam Gase is very high on him. Dysert spent the 2014 season on the Broncos’ practice squad, so he’s plenty familiar with the signal caller.
The Bears may need a viable backup for Week 1 against the Packers after Jimmy Clausen suffered a concussion in preseason. As it stands, David Fales and Shane Carden are the Bears’ other two quarterbacks, but the UDFA Carden will be released, according to Jahns. Fales has missed most of training camp with an illness.
