Florham Park, NJ -- (Sports Network) - New York Jets safety Eric Smith lost his appeal of a one-game suspension for the helmet-to-helmet hit on Arizona wide receiver Anquan Boldin and will sit out this Sunday's game against Cincinnati.

Smith was disciplined by the NFL for the hit on Boldin, who was in a defenseless position when contact was made, late in the fourth quarter of the Jets' 56-35 win in on September 28.

"His suspension was upheld, so he will be out this week," said Jets head coach Eric Mangini on Wednesday.

The play occurred with 27 seconds remaining as Boldin went up for a pass in the end zone and was hit by two players, including Smith's helmet-to-helmet collision. Boldin was tended to by medical staffs and brought off the field on a backboard and was taken to the hospital for observation.

After a series of tests performed at New York's Mt. Sinai Hospital came back negative, Boldin flew back to Arizona with the team, but had surgery for a fractured facial bone.

Smith was also fined $50,000 and will forfeit his salary for Sunday's game.
