Quarterback Green rejoins Rams as Bulger's backup

3/10/2008 - NFL Trent Green St. Louis Rams + more

Trent Green's return to the St. Louis Rams was a profitable one.

He agreed to a three-year, $8.9 million deal that included a $2.1 million signing bonus and a $900,000 roster bonus on Monday. With a $1 million base salary, Green will make $4 million in 2008.

Green, who ended last season on injured reserve after his second concussion in 13 months, was cleared to play weeks ago and had several teams, including the New Orleans Saints, looking at him as a backup quarterback. Marc Bulger will be the starter in St. Louis, but he will be backed by a quarterback who is one of the most experienced in football.

Green visited Rams Park last week and had been mulling a decision whether to keep playing. He replaces Gus Frerotte as Bulger's backup in his second stint with the Rams.

"We have now solidified our quarterback position," coach Scott Linehan said. "You will be hard-pressed to find the quality we have at that position."

Green also has a chance to reunite with offensive coordinator Al Saunders, who was hired during the offseason.

Green was released by the Dolphins last month. He played for the Kansas City Chiefs from 2001 to '06, starting every game the first five seasons and the first game of 2006 for a franchise-record 81-game streak.
