Rams' Avery leaves game vs. Pats
St. Louis Rams wide receiver Donnie Avery has left the team's exhibition game against the Patriots with a right knee injury. While the exact injury isn't known, the fear is he'll miss the entire 2010 season, a source told FOXSports.com.
Avery, who led St. Louis wide receivers with 47 catches last year, was hurt with 1:32 left in the first half Thursday night. He jumped for Sam Bradford's long pass down the right sideline, fell and clutched his right knee as the ball dropped incomplete.
''He probably has a significant knee injury,'' St. Louis coach Steve Spagnuolo told The Associated Press. ''We'll know further when we get the test.''
Before Avery was carted off the field, Patriots wide receiver Wes Welker went over and extended his hand. Welker's playing again after having surgery for a torn ACL in his left knee in February.
Avery, a second-round draft pick out of Houston in 2008, had 53 receptions as a rookie and started 28 games in his first two seasons. He caught two passes for 48 yards Thursday before the injury.
Avery first caught the eye of St. Louis during Senior Bowl practices in 2008. He displayed tremendous athleticism and physicality that week in Mobile, Alabama, and wound up being the first receiver taken off the board in that year's draft.
He's currently in the third year of his four-year rookie deal. He's listed with a base salary of $547,500.
