And then there were four.
Quarterback Gibran Hamdan sent a shock wave through the Argonauts' training camp on Friday, abruptly announcing his retirement after just two days of practice.
"The Argos are heading in a direction where they need 100% dedication and when I looked in the mirror, I knew I couldn't deliver that," Hamdan said. "My heart and dedication would not take this team to a championship and it would not be fair to my teammates, the organization and the fans to continue. I wish the Argonauts every success this season."
Hamdan's sudden departure leaves Cleo Lemon, Ken Dorsey, Dalton Bell and non-import Danny Brannagan as the Argos' quarterbacks.
Hamdan did not look great in the past couple of days, throwing a few interceptions. But in practising in a steady rain, no player has been able to show his talents completely.
"Gibran competed very well in camp but sometimes players get that feeling that it is time for them to retire," Argos head coach Jim Barker said. "We respect his decision and wish him all the best in the future."
It was thought that Hamdan, who most recently had been with the Buffalo Bills, seriously would have challenged for the No. 1 job. Lemon, who won a job over Hamdan at the Miami Dolphins' training camp in 2007, has looked the most comfortable through two days of camp.
Whether Barker will try to sign another quarterback is not known.
The Argos announced they have released non-import wide receiver Matt Lambros, who spent most of last season on the sideline with a knee injury after the Argos picked him in the 2009 draft.
