Lucas Biglia has completed his move from Anderlecht to Lazio, signing a five-year deal with the Serie A club.
The 27-year-old midfielder, who spent the last seven seasons in Belgium, has been a long-term target of the Italian club as they look to build on last season's seventh placed finish.
The two clubs have agreed terms for the player a few days ago as Biglia arrived at Lazio's summer training camp in Auronzo di Cadore to link up with his new team-mates.
But now the deal for the former Argentinos Juniors and Independiente player has officially been completed.
The club made the announcement with a statement on their official website: "SS Lazio announce that player Lucas Biglia signed with the club on a five-year deal."
Morsy, who joined the Spireites from Port Vale last month, came off in the second half of Tuesday night's friendly nursing a calf problem.
However, Lynch expects the combative midfielder to be fine for Chesterfield's final pre-season match against Sheffield Wednesday at the Proact Stadium on Saturday.
"It was just a challenge from their lad that I thought was a bit unnecessary to be honest," said Lynch following his side's 2-1 home loss to Wolves.
"He didn't need to go down the back of him. It's just stud marks down the back of his calf, it's not a pull or a strain or anything like that.
"It's nothing to worry about and I'm sure Sam, as brave as he is, won't let it affect him and he'll be ready for the next game on Saturday."
Blackburn defender Edwards, 19, had been training with the Spireites and on Tuesday signed a one-month loan deal with the League Two club.
Following the friendly defeat to Wolves, in which Edwards played 35 minutes as a second-half substitute, first-team coach Lynch said: "Ryan's come in on loan for us and is a great addition to the team. He's a very good centre-half, which is something we may need.
"I think he'll be a great addition for us. It's been well documented that we've needed someone in there and I think he'll do well for us.
"He's only just come into the side with a few day's training and after a bit longer he will bed in really well and he'll learn from us because we've got great players in our team.
"He's a fantastic player who knows the league well so I'm confident he'll do well here."
Edwards made over 30 appearances in League Two last season during loan spells at Rochdale and Fleetwood.
