GREEN BAY, Wis. Air Force 1 Yellow Outlet . - Quarterback school is back in session with the Packers. Newly signed veteran Seneca Wallace is going to have to brush up on the playbook in a hurry to get ready to back up Aaron Rodgers for Sundays season opener in San Francisco. Theres a new third quarterback in Titletown, too, after Scott Tolzien was signed to the practice squad Monday. Both quarterbacks just happened to be with the 49ers before getting picked up by the Packers. How convenient. "I think any time players are (from) a former organization, theres always (a thinking that) immediately theyre going to tell you everything about the 49ers," coach Mike McCarthy said. "Scott and Seneca both are more focused on getting ready for the game so they definitely can give you insight." More so Tolzien than Wallace. Tolzien was a backup the last two years for the 49ers, but never played in a game. Wallace was only in San Francisco for a week this preseason, competing for a backup job behind Colin Kaepernick. But its Wallace whos going to be Rodgers understudy. Its quite a turnaround from last week, when he was languishing behind Kaepernick, Colt McCoy and B.J. Daniels on the 49ers depth chart. When asked then, coach Jim Harbaugh said Wallace was "not going to continue to play football," lending to speculation to whether Wallace decided to retire. Not so, Wallace said Monday after his first Packers practice. "No, no. Its just miscommunication between me and Harbaugh. We talked about it. I called him to communicate that to him," Wallace said. "It was just pretty much miscommunication between me and him." After being drafted by the Seahawks in 2003 out of Iowa State, Wallace went on to play seven seasons in Seattle. Hes also had stops with the Browns and Saints. In 21 starts and 62 career games, Wallace has completed 59 per cent of passes (452 of 764) for 4,808 yards and 31 touchdowns, along with 18 interceptions. In a relatively young locker room, Wallace, a 10-year veteran, immediately becomes the most experienced player on offence. Only defensive tackle Ryan Pickett has more NFL experience with 13 seasons. Its that experience that drew McCarthy to his new backup. Wallace had time in a West Coast offence in Seattle under former coach Mike Holmgren, who used to coach the Packers. McCarthy said Wallace ran similar no-huddle schemes in Cleveland. Also, Wallace was drafted in Seattle while current Packers general manager Ted Thompson was the vice-president of football operations there. With Wallace and Tolzien, Green Bay is starting anew in its quest to find a capable backup to Rodgers after already jettisoning three candidates in the last several weeks. Graham Harrell is now with the Jets. Vince Young was cut over the weekend. B.J. Coleman was released after Wallace was signed. Wallaces journeyman background might also help him out. "Hes been a backup quarterback primarily his whole career. He clearly understands the role, has a lot of experience in an out of systems," McCarthy said. "Just talking football with him last night, I felt confident that hell be ready to play Sunday." Wallace was appreciative of the new opportunity. He gave thoughtful responses to questions from reporters, as if a wise sage offering advice to a rookie on life in NFL. While he wouldnt mind starting, Wallace is clearly comfortable with his role. Hes not going to supplant Rodgers, the 2011 NFL Most Valuable Player. "You cant let that get to you. Thats part of it. Were blessed to play a sport that most people dream to do," he said. "The ones who stay around for a long period of time are the ones who get it." So there was Wallace on Monday on the practice field, watching several feet behind Rodgers as the offence ran through drills. Wallace walking alongside Rodgers during a break, where the two looked like they were talking shop. And Rodgers running through a quarterback drop for Wallace on a particularly quick pass play. "It was a tough couple weeks, Wallace said, "but what happened is behind me and now Im moving forward and focusing on being here in Green Bay and being the best provider as a backup to A-Rod." Notes: Tolzien returned to the state where he played college ball at Wisconsin. ... After competing all preseason with Marshall Newhouse, Don Barclay started at right tackle. But Barclay said he doesnt think the competition is settled, and McCarthy indicated Newhouse would play Sunday regardless ... CB Casey Hayward (hamstring) didnt take part in practice. Two starters sidelined last week by sore hamstrings, S Morgan Burnett and LB Brad Jones, returned ... Besides Tolzien, the Packers also signed OL Aaron Adams and Bryan Collins; RB Michael Hill; WRs Charles Johnson and Myles White; CB James Nixon; and TE Jake Stoneburner to their practice squad. The latter four players were with the team during training camp. Air Force 1 Store .

The transfer fee for what Arsenal called a "long-term" deal was undisclosed but is thought to be in the region of 16 million euros ($27 million). Chambers continues the exodus of players from Southampton this summer, following the departures of Adam Lallana, Rickie Lambert and Dejan Lovren to Liverpool and Luke Shaw to Manchester United. "We are very pleased that Calum has agreed to join us," Arsenal manager Arsene Wenger said. "The way he adapted to the Premier League last season with Southampton at a young age shows that he has tremendous quality. "He has a lot of the attributes that we look for in a young player and I am sure that he will do well with us." Chambers, who is currently captain of the England under-19 side, made his Premier League debut on the opening day of lasst season and went on to appear in 22 league games. Air Force 1 Grey Store. "I am so happy to be signing for Arsenal," Chambers said. "They are a team I have much admired for their playing style, and a team who have been one of the top sides in Europe for many years. "Im looking forward to joining up with my new teammates today and beginning preparation for the season ahead." Southampton indicated it had no choice. "Calum made it clear to us that he did not see his future at Southampton," executive director Les Reed said. "As such, it was crucial that we were able to negotiate a substantial fee that also reflects the work our staff have put into Calums development since he joined the club at the age of eight. "Our position remains unchanged in that we are determined to keep our best young players at the club ... It is important in the transfer window to remain calm, resilient and above all patient. We have targets, and we are working hard to get them across the line." ' ' '
