Cardinals make roster moves

The Cardinals made some roster moves on Wednesday, signing running back Thomas Clayton and guard/center Rich Ohrnberger. The team also released wide receiver Stanley Arukwe and waived injured center Ryan Bartholomew (knee).

Clayton appeared in three games with the Browns last season, and had eight carries for 12 yards. In 2010, Clayton also played in three games, one with the Patriots and two with the Browns.

Clayton was selected by the 49ers in the 2007 NFL Draft out of Kansas State.

Clayton will wear jersey #31.

Ohrnberger spent the past three seasons as a member of the Patriots, appearing in five games. He missed the entire 2011 season after being put on injured reserve last September.

Ohrnberger was originally drafted by New England in the fourth round of the 2009 NFL Draft out of Penn State.

Ohrnberger will wear jersey #72.
