TAMPA, Fla. -- The field at University of Phoenix Stadium finished first among grass fields in the NFL Players Association's annual survey.

The 49ers' field ranked 12th out of 18 grass fields. The top five: Arizona, Tampa Bay, San Diego, Carolina and Jacksonville. The five worst: Pittsburgh, Oakland, Miami, Chicago and Green Bay.

The FieldTurf surface at Qwest Field in Seattle ranked second among artificial infilled surfaces, behind the new field at Lucas Oil Stadium in Indianapolis. The Rams' FieldTurf surface ranked eighth out of 13 artificial infilled surfaces. The five best: Indianapolis, Seattle, Baltimore, Atlanta and Detroit. The five worst: Dallas, Minnesota, Giants/Jets, St. Louis and Buffalo.

Players voted for the best and worst surfaces separately. That explains how the Rams' surface ranked eighth-best and fourth-worst out of 13 surfaces.
