A minor tweet from Allen Iverson prompted a major signing announcement from the Memphis Grizzlies.

The Grizzlies confirmed Wednesday they had reached a tentative agreement with Iverson, a four-time NBA scoring champion and the league's most valuable player in 2001.

Earlier in the day, Iverson wrote on his Twitter account that "God chose Memphis as the place that I will continue my career."

"We anticipate signing him to a contract very soon," Grizzlies general manager Chris Wallace said, confirming that a media conference is slated for Thursday.

Iverson, 34, reportedly agreed to a one-year contract worth $3.5 million US, a far cry from the $21 million US he pocketed last season.

As is the norm in the NBA, the pact is pending him passing a physical.

"I think the process and the waiting has been difficult for him and his family," said Leon Rose, Iverson's agent. "I think he is relieved that it is over and excited about the opportunity to go play for Memphis."

Iverson, a lightning-quick point guard, struck a deal Monday in a meeting with Grizzlies owner Michael Heisley, head coach Lionel Hollins and Wallace.

The perennial all-star is the highest profile player to agree to suit up for the Grizzlies, who entered the NBA as an expansion team in Vancouver in 1995-96.

"I feel that they are committed to developing a winner and I know that I can help them to accomplish that," Iverson tweeted. "I feel that I can trust them."

Memphis went 24-58 last season — tied with the Minnesota Timberwolves for the fifth-worst record in the NBA — and ranked 29th out of 30th in scoring.

Iverson split last season between the Denver Nuggets and Detroit Pistons, averaging 17.5 points, 5.0 assists, 3.0 rebounds, 1.5 steals and 36.7 minutes in 57 games.

He has averaged 27.1 points, 6.2 assists, 3.7 rebounds, 2.2 steals and 41.4 minutes in 886 NBA games since he was drafted first overall out of Georgetown by the Philadelphia 76ers in 1996.
