DAVIE, Fla., Oct. 20 (UPI) -- Miami Dolphins quarterback Trent Green's 2007 season ended Saturday due to a Grade 3 concussion suffered Oct. 7 against Houston.
It was the second serious head injury in as many seasons for the 37-year-old Green, who has been placed on the injured reserve list. He also suffered a severe concussion in the 2006 season opener, which caused him to miss half the season.
"At this point, this is the best thing for Trent and the team," Dolphins Coach Cam Cameron said on the team’s Web site. “The doctors have prescribed rest for now."
The Dolphins acquired Green from Kansas City in the off-season in exchange for a draft pick based on the two-time Pro Bowl quarterback's playing time this season.
"I realize this is in the best interest of my long-term health and I want nothing but the best for the team," Green said. "I have not made any decisions about my future."
