Geno Smith practices, ready to play ... uh, sit on bench

FLORHAM PARK, N.J. -- Geno Smith will be the New York Jets' No. 2 quarterback Sunday against the Kansas City Chiefs.

After resting his ailing right shoulder Wednesday, Smith resumed throwing and participated in a full practice Thursday. The former starter threw about 50 balls, according to Rex Ryan. He expects Smith to be ready for the game, backing up Michael Vick.

"That's what it looks like," Ryan said. "I would expect, unless there's some kind of setback, that he would be the backup quarterback."

Smith hurt his throwing shoulder in last Sunday's loss to the Buffalo Bills. He apparently hurt it twice during his 11-play stint, but he didn't notify anyone until later in the game. Calling it a "harsh reality" of the situation, Ryan said Smith probably would've continued to play if he hadn't thrown three interceptions, resulting in his benching.

Meanwhile, the Jets have an issue at cornerback. So what else is new? Darrin Walls, their most dependable corner, appears unlikely to play after missing his second day with calf and knee injuries. That means they will start Antonio Allen ... and pick one: Phillip Adams or Kyle Wilson or Josh Thomas or Marcus Williams. They've been changing personnel so much at cornerback that defensive coordinator Dennis Thurman, speaking to reporters, said he knows Thomas and Williams by their numbers, not their names.
