The Jets signed DT Daniel Muir on Wednesday and placed LB Josh Mauga on injured reserve with a pectoral injury.
Muir has appeared in 43 games with 26 starts and has 108 tackles. He had 11 tackles in four games for the Colts last season. He spent the preseason with the Packers and had nine tackles. Muir adds depth at defensive tackle, as the Jets are expected to be without NT Kenrick Ellis for some time.
Mauga tore his pectoral muscle in Monday night's loss to Houston.
