Seymour injury not serious

Patriots defensive end Richard Seymour left today's game in the second quarter with a back injury and did not return, but the injury is not considered serious, according to a league source.

Seymour took a shot to his lower back on a third-and-10 play with 1:35 remaining in the second quarter, when Cardinals quarterback Kurt Warner couldn't connect with running back Edgerrin James on a screen pass.

A league source described the injury as nothing major.

[Update. midnight] Here is the section on Seymour from Monday's Patriots Notebook in the Boston Globe:

Defensive end Richard Seymour left in the second quarter with a back injury and did not return. He took a shot to his lower back when Warner couldn't connect with running back Edgerrin James on a screen pass on a third-and-10 play with 1:35 left in the half.

A league source indicated Seymour was in pain after the game. The injury, although not initially considered major in nature, could potentially affect Seymour's availability for Sunday's season finale in Buffalo.

Seymour tied his career high for sacks in a season (eight) when he split a sack with Mike Wright late in the first quarter.
