TEMPE, Ariz. -- As of Monday, the Arizona Cardinals weren't in a rush to sign another quarterback this week, but that may change by Tuesday or Wednesday if they believe Carson Palmer and Drew Stanton won't be healthy enough to be active Sunday against Washington.

Arizona coach Bruce Arians said if the Cardinals bring in another quarterback, it'll be “somebody hopefully that knows what our protections are and can possibly be a backup.” That statement narrowed the list of potential signees significantly to someone who had played in Arians' system.

Here are five quarterbacks with prior ties to Arians who the Cardinals may target this week:

• Ryan Lindley: Currently on the San Diego Chargers practice squad, Lindley would make the most sense. He spent 2013 as Arizona's third-string backup and was released in August, so he has the most knowledge of the Cardinals' offense of anyone not on the current roster.

• Chandler Harnish: Currently on the Minnesota Vikings practice squad, Harnish spent 2012 with Arians and Drew Stanton as Indianapolis' third-string quarterback.

• Dennis Dixon: Dixon, a free agent, is the youngest of Arians' former backup quarterbacks from his Pittsburgh Steelers days.

• Charlie Batch: He's 39 and an absolute long-shot but was on the Steelers for six years with Arians, including the five as offensive coordinator. He knows the Arians' scheme about as well as anyone but hasn't played since 2012.

• Byron Leftwich: Also hasn't played since 2012 but spent two years under Arians in Pittsburgh. At 34, he may have enough gas in the tank to be a backup and tutor Logan Thomas.
