WHITE SULPHUR SPRINGS, W. Va. — The shuffling at tight end continues.

The Saints placed tight end Kevin Brock on injured reserve on Wednesday and brought back Alex Smith, who was released earlier this week.

Brock was knocked out of Tuesday’s practice during positional drills and had to be carted from the sidelines. He was signed by New Orleans in late July.

Smith was released earlier this week and replaced by former third-round pick Michael Egnew.

As reported Tuesday, defensive tackle Austin Brown has officially been waived with an injury designation. David Hunter was signed to take his place.
