TEMPE, Ariz. -- The Logan Thomas Experiment lasted one practice.
The Week 17 move comes a few days after Arians said Thomas would start and play at least a half. But through it all, Arians gave himself an out, saying he would be quick to give Thomas the "hook" -- even going as far as saying he could change his mind during the week of practice.
Apparently, it took just one day of watching Thomas practice for Arians to make the move.
Arians said after Wednesday's practice that Thomas had a "shaky" start but finished "pretty strong."
Arians doesn't speak to the media on Thursdays. Offensive coordinator Harold Goodwin said he didn't have a comment about Lindley starting.
"Guess we'll see what happens on Sunday," Goodwin said.
Goodwin said all three quarterbacks -- Lindley, Thomas and rookie Jeff Mathews, on the practice squad -- had a good practice Thursday.
"He's a confident kid," Goodwin said of Thomas. "We have confidence in him and we'll just go from there."
Lindley was 18-for-44 for 216 yards and an interception in Sunday night's 35-6 loss to the Seattle Seahawks. He hasn't thrown a touchdown in an NFL-record 225 consecutive pass attempts, according to the Elias Sports Bureau.
Lindley is 1-4 as a starter and has a career completion percentage of 50.6. He's thrown eight interceptions to his zero touchdowns. And on throws of 20 yards or longer, Lindley is 2 for 29, according to ESPN Stats & Information.
