From Schneidman: 

Packers will have joint practices with the Colts in Indy and Seahawks in Green Bay this summer, per source. Those sessions will precede second and third preseason games.

The Packers got good work in against the Broncos and Ravens last summer and hope to do so again with the Colts and Seahawks.

NFL teams are permitted to hold joint practices for as many as four days during training camp, and those can be divided in any way possible. 

No word yet how many practices the Packers will have against each team but there's a good chance each session will be limited to one joint practice each. Last summer, Packers head coach Matt LaFleur mentioned his team's joint practices with the Patriots a few years ago as an example of what can happen when teams get after it for multiple days in the dog days of summer. After the first day with the Patriots went by without any major incidents, three fights broke out about five minutes into their second joint practice. 

Expect to have an official announcement from the team soon on dates and timing.
